The fastest card is a 7900 series. The "GTX" may not be the only fast one though, the 7900GTO and 7950GT both come with the same amount of RAM (512MB, although some are 256mb) and all of the pixel shaders.
My 7900GS has some of the units turned off until it has the same as a 7800GTX.
BUT, mine is clocked at 650mhz! I don't think it is easy to do that with a 7800 series card because it is a 110nm technology card, not a 90nm card like the 7900 series.
Note that I did a voltmod and attached much better cooling to my 7900GS, but a 7900GT/7950GT/GTX/GTO may come with better cooling, and the voltmod is unnecessary (I simply used a jumper to connect what is software configured voltage on the 7900GT+ cards)
7900 cards with 512MB of ram are easy to get: $80 for a buy it now, $10 shipping

Although I would recommend a heatpipe cooler version for en extra $20 as it will allow overclocking, and these cards can really overclock well.
On the subject of the screens, it is very important that you use 45° and 135° glasses and one eye is completely blank as you look normally at the monitor you intend to use. Monitors polarized on a 90° or 180° angle will not work, the mirror can't switch them because they are entirely vertical/horizontal lines.
Check out what is possible, here is my rig:

Beware that you will be spoiled for any other method of gaming :), and be forced to wait for the iZ3D driver support to play any games that the 7900 series can't handle.
Good news is that the 7900 is a pretty decent card and you can use lower resolutions because each eye gets its own resolution, thus you aren't missing detail.

Just to add a little. If you are planning on using Shutterglasses and playing newer games:
an 8800GTS 320MB may be the card you are looking for. Here is how to use it in S3D with shutterglasses [url="http://www.mtbs3d.com/phpBB/viewtopic.php?t=1072"]http://www.mtbs3d.com/phpBB/viewtopic.php?t=1072[/url]
If you use the proper driver in Windows XP they work with shutter-glasses (All I know is that it flickered like crazy and displayed very well), it did NOT work with Planar (mirrored LCD), although if iZ3D comes out with a proper driver it will. (It will work with direct Dual Polarized projectors, iZ3D has dual out support :) )
They are actually about the same cost as a 7900 series card! Despite being about twice as fast in newer games.
Note that these are just the affordable G80 chip cards, the 8800GTS 640MB will work as well as the 320mb one. Also the 8800GTX with a G80 chip should work. The cards that DON'T work are the ones with 256mb, 512mb, 384mb (on a 192-bit memory bus). When in doubt check if it is based on a G92 Core, that is the one that doesn't work.

There seems to be so many solutions. So is there somewhere a list where the 3D-Quality is compared? How good the 3D is and how many problems occur?
The price would be interesting too but I think I would buy used hardware so it would be cheaper...
I see this solutions at the moment:
1.) Shutterglasses with CRT (Will be dark. Maybe half of the normal brightness. Possibly desyncs.)
2.) Shutterglasses with DLP-Projector (Will be dark too I think.)
3.) Polarized Setup with 2 DLP-Projector or 2 LCD-Projector (Will be brighter than shutterglasses and maybe problems with ghosting.)
4.) 3D-Monitor. (Should be normal brightess but ghosting.)
5.) 2 TFT parallel or top-down with a semipermeable mirror. (Normal brightness)
Is there some more? (Anaglyph isnt a solution for me because the wrong colors.) And what of these solutions will bring the best 3D?
I think the costs will be from most to less this chronology (If buying used hardware):

At the moment number 2 or 5 sounds most interesting to me. Disadvantiges are the dark image with shutterglasses and the small screen with the 2 TFTs (I dont think I can buy 2 30" Displays... /smile2.gif' class='bbc_emoticon' alt=':))' /> But at the other hand, if the screen-resolution can be set high on the tft it would be big enough when sitting near the mirror.
On the other hand... Im not the pro in physics but it shouldnt be a problem to get a bigger screen with a set of lenses. But... lenses in this size would cost a lot I think... But maybe there is a cheap solution?
But at the end I think the 2-Display-TFT sounds most interesting to me. The costs arent so bad. Technical knowledge isnt needed too much when setting up the screens parallel. And the image in my association could be the best.
But I dont know how the 3D will occur. The light would be normal light isnt it? So how comes here one image to the one and one to the other eye?
At the moment Im using a 7800GTX. I bought this one because of the number of pipelines he has. I thought this would be an advantage. Here is a ranking of cards: [url="http://www.3dchip.de/Grafikchipliste/Leistung_Graka.htm"]http://www.3dchip.de/Grafikchipliste/Leistung_Graka.htm[/url]
I didnt overclocked this one because I normally only came out with 10-15% more power or so when I overclocked a card. So I didnt see a big advantage in doing so when framerate is going from 20 to 23 frames...
A Voltmod is one of the overclocking utilities that make the displaycard live less long I have read.
By the way, how to find the right glasses? They must be polarized for 2 TFT but which way?

45° and 135° glasses? How do I know which way the glasses are polarized? And the same for the monitors? At the moment I dont see how it works. How is the light polarized when using 2 same monitors?
Polarized on 90° and 180° means that the light coming out is directed this way?
And the second thing is. Normally the drivers from NVIDIA or iz3d are only for their monitors or the glasses. Can they used freely for other TFT, projector and so on?

By the way... Instead of buying big lenses and put them before the mirror to get a bigger screen it should be possible to build smaller lenses to the polarized glasses. Similar to binoculars.
I think this way a bigger screen could be built. Maybe even with small TFTs... (But having the max resolution of them in mind...)
Nonsense thought or possible? For normal tfts using glasses wouldnt be good but with 3D glasses will be used anyway...

The best seems so far to use a silverscreen with two projectors (if you want to easily show others 3d as well. One pair of polarized glasses/person is enough for effect). If you use lcd-projectors you're able to have either ordinary linear polarizers (45% light throughput) or special stereopol-polarizer (90% light throughput). Beware though: Those filters are really expensive (one pair appr. at the same cost as one projector). You can use this setup for older games using nvidiastereo and for newer games using for example the iz3d-driver (think tridef drivers works too). The ghostingrejection is about 85-90% which is far more better than i had with shutters/philips crt. There has to be very high contrasts for the ghosting to even be noticeable. You can check [url="http://www.mtbs3d.com/phpBB/viewtopic.php?t=861"][b]here[/b][/url] for some practical comparisons. Since two outputs probably will be supported as long as there is stereo-3d i would say it's the most futuresafe option since more or less all present stereodrivers support this (well... not nvidia anymore :blink:). All of course depends on softwaresupport.
The backsides with passive projection: Really expensive. You need two projectors, a silverscreen plus filters. Since two projectors are needed the bulb cost also counts. Aligning the projectors can be slight tricky but shouldn't practically cause any problems. If wrongfully aligned you'll have a skewed vision, like the screen is twisted.
Cheaper way if you want to go big is using a dlp-projector in combination with shutterglasses. Each person have to wear one pair of shutterglasses for effect but since only one projector is needed... Ghostingrejection should be even better than a passive projection rig but you need to check that the projector can handle stereo-3d (either borrow one for test or check other person success). You only need a white wall for this setup. But still: You need softwaresupport which probably will come from iz3d in a soon future. Don't count on nvidia but at least you can play older games in 3d if you have an "old high end" card like the 7950 or lower. :">
Some hdtv's also works with shutters but even here you need to check up stereo-3d compability.

You didn't understand, the 7900 is clocked 50% more from the start. The 7800 is old 110nm process, the 7900 is a newer chip on 90nm process. Less heat, less electricity usage, also faster memory as well.
All the cards I showed you are used. I don't know where you got the idea that they are new. About 50 Euro for a 7900 or 8800 is a good deal.

I didnt noticed you built such a planar solution. Now I found your pictures... Looks good. Do you have built 2 Versions of this technique? One on top of another and one parallel?
Is one of these solutions better in any way? I presume that this doesnt change anything about the polarization of 45 degrees isnt it?
You didnt made the TFT to a 90° angel together. Why not 90°? Doesnt make that a distorted image? *dont know*
>I don't know where you got the idea that they are new. About 50 Euro for a 7900 or 8800 is a good deal.
I meant a new used one... :) Do you think I need one for planar-tft? Till now I could play Oblivion with 1920x something and didnt have a bigger loss of framerates. But Oblivion is some years old now I think...
The link you gave me where the glasses are sold shows 45° glasses. That are the ones that are suitable. At your imagegallery you are showing some good pictures with the glasses. Looks good to me. Only a little bit ghosting on the images. Can the rest of ghosting be disabled with better glasses? Where comes the ghosting from? Are the glasses letting in not only the special polarized light? Or does the TFT send not only the special polarized one?
So when planning on buying new (used /smile2.gif' class='bbc_emoticon' alt=':))' /> tfts for that is there somewhere wrote in specs about the polarized light? I think I didnt have read such spec till now. Dont want to buy TFTs and at the end they dont work...
At the end... Did you have the chance of comparing your solution with a dual-projector-solution? Whats your opinion?
@Likay
2 Projectors would be a bit expensive for me, even when buying used one. And using only one with shutterglasses... I dont know... because shutterglasses make the image dark, every user has to use a shutterglass and I dont know if I wouldnt have again problems with the syncing...
At the moment the most interesting thing would be this planar-thing. Two TFT when they are used arent to expensive, a mirror maybe from a local manufacturer (like described in a thread) and building a rack (I trust me I can handle it). Then only using glasses...
Sound at the moment like the best solution for me. Bright Image, low cost and maybe with modified glasses the image could be big like with a projector. I mean a set of 4 lenses that can do this for each glasses should be possible... In physics they used a convex and a concave lense to get a bigger image...

I don't notice much ghosting at all, important is a good stiff mirror, glass with a frame of some kind is best (I only have a plastic mirror with no frame).
The ghosting is partially because it isn't lined up precisely, and partially because of the camera. In a normal lit room (60watt bulb in ceiling) I don't see any ghosting.

The specs don't usually tell you the polarization angle, it would be good to test it first.
Maybe there is a local Computer shop or computer lab that you could check monitors.

[/quote]If I had the money I would use circular polarized filters on DLP projectors. I tried a setup with dual LCD projectors (this only works on single panel LCD projectors with 45° polarization), but they were poor quality projectors.
You need a silver screen to preserve the polarization. With a good quality DLP you should be able to have a very large screen. DLP needs the bulb replaced every 3,000 hours or so, and it is expensive usually. I am waiting for the ones that have 3 lasers instead of a bulb, that way you don't need to replace bulbs: [url="http://www.novalux.com/display/"]http://www.novalux.com/display/[/url]

You need a silver screen to preserve the polarization. With a good quality DLP you should be able to have a very large screen. DLP needs the bulb replaced every 3,000 hours or so, and it is expensive usually. I am waiting for the ones that have 3 lasers instead of a bulb, that way you don't need to replace bulbs: http://www.novalux.com/display/
(plus I have no money at all, I need employment :( )
[quote name='SebastianJu' date='Aug 6 2008, 02:25 AM']Didnt you mention in the other thread that you bought another mirror from a local glass manufacturer? Wasnt that mirror good at all?
I dont have much money at the moment too... Going into the stores to look at the monitors is a good idea....

No, that was a different person. I haven't checked for glass locally.
As far as I know it is just a 2-way mirror with a little less of the reflective stuff on it (or maybe a 2-way mirror would work fine with a little adjustment.)
Don't sweat all the TFT and half-mirror stuff, just grab a standard hand mirror and any two monitors and try this:
Two CRT's work, one crt and one lcd works. they can even be two different sizes as long as they are close (15" LCD and 17" CRT for example, or 15" CRT and 17" CRT)
The important thing is to get the picture lined up in the mirror. You could even cheat and use the adjustments on the larger screen to make the whole image smaller (look for Horizontal and Vertical size adjustments), and the image on the smaller screen just a little bigger (so some of the info is off the screen.)
Most important, just have fun.
The setup I link to here is kind of a HMD (head mounted display), but on your desktop. This means that you can't move your head or it doesn't work well. The bonus with directly-viewed screens is that you don't have any ghosting at all because each eye is actually looking in a different direction.

I think the best solution by far is a Samsung DLP (and there's someone else that also makes 3D DLPs, i forget). This is also one of the cheapest and most user-friendly solutions (it's even wife-approved). If you look around you can buy a good 1080p 61" for about $1000. It will only work with shutter glasses, but you can have everyone in the room enjoy the experience, since it's not limited to where your head is. There's also no cumbersome mirrors, lenses, etc. These displays work at 120Hz, so there's no flickering, no ghosting, and no loss of resolution, color, detail, etc. Best of all, you also have a dual purpose TV for the living room. If you use the built-in Vista Media Center (which is excellent IMO) and you've got your own HDTV tivo / DVD player / game console solution in one neat package. This can be a great bullet point when trying to sell this setup to your spouse.
Only problem is that you have to use the Tridef software which is far from optimized and is not DX10. Expect a severe drop in framerates. On the other hand, since nvidia refuses to support checkerboarding, you can go with any video card manufacturer out there since the drivers are all third party from tridef (crappy as they are).

The fastest card is a 7900 series. The "GTX" may not be the only fast one though, the 7900GTO and 7950GT both come with the same amount of RAM (512MB, although some are 256mb) and all of the pixel shaders.
My 7900GS has some of the units turned off until it has the same as a 7800GTX.
BUT, mine is clocked at 650mhz! I don't think it is easy to do that with a 7800 series card because it is a 110nm technology card, not a 90nm card like the 7900 series.
Note that I did a voltmod and attached much better cooling to my 7900GS, but a 7900GT/7950GT/GTX/GTO may come with better cooling, and the voltmod is unnecessary (I simply used a jumper to connect what is software configured voltage on the 7900GT+ cards)
7900 cards with 512MB of ram are easy to get: $80 for a buy it now, $10 shipping

Although I would recommend a heatpipe cooler version for en extra $20 as it will allow overclocking, and these cards can really overclock well.
On the subject of the screens, it is very important that you use 45° and 135° glasses and one eye is completely blank as you look normally at the monitor you intend to use. Monitors polarized on a 90° or 180° angle will not work, the mirror can't switch them because they are entirely vertical/horizontal lines.

Beware that you will be spoiled for any other method of gaming :), and be forced to wait for the iZ3D driver support to play any games that the 7900 series can't handle.
Good news is that the 7900 is a pretty decent card and you can use lower resolutions because each eye gets its own resolution, thus you aren't missing detail.

an 8800GTS 320MB may be the card you are looking for. Here is how to use it in S3D with shutterglasses [url="http://www.mtbs3d.com/phpBB/viewtopic.php?t=1072"]http://www.mtbs3d.com/phpBB/viewtopic.php?t=1072[/url]
If you use the proper driver in Windows XP they work with shutter-glasses (All I know is that it flickered like crazy and displayed very well), it did NOT work with Planar (mirrored LCD), although if iZ3D comes out with a proper driver it will. (It will work with direct Dual Polarized projectors, iZ3D has dual out support :) )
They are actually about the same cost as a 7900 series card! Despite being about twice as fast in newer games.

Note that these are just the affordable G80 chip cards, the 8800GTS 640MB will work as well as the 320mb one. Also the 8800GTX with a G80 chip should work. The cards that DON'T work are the ones with 256mb, 512mb, 384mb (on a 192-bit memory bus). When in doubt check if it is based on a G92 Core, that is the one that doesn't work.

The price would be interesting too but I think I would buy used hardware so it would be cheaper...
I see this solutions at the moment:
1.) Shutterglasses with CRT (Will be dark. Maybe half of the normal brightness. Possibly desyncs.)
2.) Shutterglasses with DLP-Projector (Will be dark too I think.)
3.) Polarized Setup with 2 DLP-Projector or 2 LCD-Projector (Will be brighter than shutterglasses and maybe problems with ghosting.)
4.) 3D-Monitor. (Should be normal brightess but ghosting.)
5.) 2 TFT parallel or top-down with a semipermeable mirror. (Normal brightness)
Is there some more? (Anaglyph isnt a solution for me because the wrong colors.) And what of these solutions will bring the best 3D?
I think the costs will be from most to less this chronology (If buying used hardware):
3

At the moment number 2 or 5 sounds most interesting to me. Disadvantiges are the dark image with shutterglasses and the small screen with the 2 TFTs (I dont think I can buy 2 30" Displays...
On the other hand... Im not the pro in physics but it shouldnt be a problem to get a bigger screen with a set of lenses. But... lenses in this size would cost a lot I think... But maybe there is a cheap solution?
But at the end I think the 2-Display-TFT sounds most interesting to me. The costs arent so bad. Technical knowledge isnt needed too much when setting up the screens parallel. And the image in my association could be the best.
But I dont know how the 3D will occur. The light would be normal light isnt it? So how comes here one image to the one and one to the other eye?
At the moment Im using a 7800GTX. I bought this one because of the number of pipelines he has. I thought this would be an advantage. Here is a ranking of cards: [url="http://www.3dchip.de/Grafikchipliste/Leistung_Graka.htm"]http://www.3dchip.de/Grafikchipliste/Leistung_Graka.htm[/url]
I didnt overclocked this one because I normally only came out with 10-15% more power or so when I overclocked a card. So I didnt see a big advantage in doing so when framerate is going from 20 to 23 frames...
A Voltmod is one of the overclocking utilities that make the displaycard live less long I have read.
By the way, how to find the right glasses? They must be polarized for 2 TFT but which way?

45° and 135° glasses? How do I know which way the glasses are polarized? And the same for the monitors? At the moment I dont see how it works. How is the light polarized when using 2 same monitors?
Polarized on 90° and 180° means that the light coming out is directed this way?
And the second thing is. Normally the drivers from NVIDIA or iz3d are only for their monitors or the glasses. Can they used freely for other TFT, projector and so on?
A new displaycard would be a at the end of buying list. Or is a new one needed for me?

I think this way a bigger screen could be built. Maybe even with small TFTs... (But having the max resolution of them in mind...)
Nonsense thought or possible? For normal tfts using glasses wouldnt be good but with 3D glasses will be used anyway...

The backsides with passive projection: Really expensive. You need two projectors, a silverscreen plus filters. Since two projectors are needed the bulb cost also counts. Aligning the projectors can be slight tricky but shouldn't practically cause any problems. If wrongfully aligned you'll have a skewed vision, like the screen is twisted.
Cheaper way if you want to go big is using a dlp-projector in combination with shutterglasses. Each person have to wear one pair of shutterglasses for effect but since only one projector is needed... Ghostingrejection should be even better than a passive projection rig but you need to check that the projector can handle stereo-3d (either borrow one for test or check other person success). You only need a white wall for this setup. But still: You need softwaresupport which probably will come from iz3d in a soon future. Don't count on nvidia but at least you can play older games in 3d if you have an "old high end" card like the 7950 or lower. :">
Some hdtv's also works with shutters but even here you need to check up stereo-3d compability.

You didn't understand, the 7900 is clocked 50% more from the start. The 7800 is old 110nm process, the 7900 is a newer chip on 90nm process. Less heat, less electricity usage, also faster memory as well.
All the cards I showed you are used. I don't know where you got the idea that they are new. About 50 Euro for a 7900 or 8800 is a good deal.

I didnt noticed you built such a planar solution. Now I found your pictures... Looks good. Do you have built 2 Versions of this technique? One on top of another and one parallel?
Is one of these solutions better in any way? I presume that this doesnt change anything about the polarization of 45 degrees isnt it?
You didnt made the TFT to a 90° angel together. Why not 90°? Doesnt make that a distorted image? *dont know*
>I don't know where you got the idea that they are new. About 50 Euro for a 7900 or 8800 is a good deal.
I meant a new used one... :) Do you think I need one for planar-tft? Till now I could play Oblivion with 1920x something and didnt have a bigger loss of framerates. But Oblivion is some years old now I think...
The link you gave me where the glasses are sold shows 45° glasses. That are the ones that are suitable. At your imagegallery you are showing some good pictures with the glasses. Looks good to me. Only a little bit ghosting on the images. Can the rest of ghosting be disabled with better glasses? Where comes the ghosting from? Are the glasses letting in not only the special polarized light? Or does the TFT send not only the special polarized one?
So when planning on buying new (used
At the end... Did you have the chance of comparing your solution with a dual-projector-solution? Whats your opinion?
@Likay
2 Projectors would be a bit expensive for me, even when buying used one. And using only one with shutterglasses... I dont know... because shutterglasses make the image dark, every user has to use a shutterglass and I dont know if I wouldnt have again problems with the syncing...
At the moment the most interesting thing would be this planar-thing. Two TFT when they are used arent to expensive, a mirror maybe from a local manufacturer (like described in a thread) and building a rack (I trust me I can handle it). Then only using glasses...
Sound at the moment like the best solution for me. Bright Image, low cost and maybe with modified glasses the image could be big like with a projector. I mean a set of 4 lenses that can do this for each glasses should be possible... In physics they used a convex and a concave lense to get a bigger image...

The link you gave me where the glasses are sold shows 45° glasses. That are the ones that are suitable. At your imagegallery you are showing some good pictures with the glasses. Looks good to me. Only a little bit ghosting on the images. Can the rest of ghosting be disabled with better glasses? Where comes the ghosting from? Are the glasses letting in not only the special polarized light? Or does the TFT send not only the special polarized one?
So when planning on buying new (used
At the end... Did you have the chance of comparing your solution with a dual-projector-solution? Whats your opinion?
@Likay
2 Projectors would be a bit expensive for me, even when buying used one. And using only one with shutterglasses... I dont know... because shutterglasses make the image dark, every user has to use a shutterglass and I dont know if I wouldnt have again problems with the syncing...
At the moment the most interesting thing would be this planar-thing. Two TFT when they are used arent to expensive, a mirror maybe from a local manufacturer (like described in a thread) and building a rack (I trust me I can handle it). Then only using glasses...
Sound at the moment like the best solution for me. Bright Image, low cost and maybe with modified glasses the image could be big like with a projector. I mean a set of 4 lenses that can do this for each glasses should be possible... In physics they used a convex and a concave lense to get a bigger image...

I didnt noticed you built such a planar solution. Now I found your pictures... Looks good. Do you have built 2 Versions of this technique? One on top of another and one parallel?
Is one of these solutions better in any way? I presume that this doesnt change anything about the polarization of 45 degrees isnt it?
You didnt made the TFT to a 90° angel together. Why not 90°? Doesnt make that a distorted image? *dont know*[/quote]
I don't know, it seems ok by me, but I made mine adjustable just in case it wouldn't work. The real ones from Planar say it is a 110° angle between the screens: [url="http://www.planar3d.com/"]http://www.planar3d.com/[/url]

You probably don't need a new card at all if your program runs just fine.

I don't notice much ghosting at all, important is a good stiff mirror, glass with a frame of some kind is best (I only have a plastic mirror with no frame).
The ghosting is partially because it isn't lined up precisely, and partially because of the camera. In a normal lit room (60watt bulb in ceiling) I don't see any ghosting.

The specs don't usually tell you the polarization angle, it would be good to test it first.
Maybe there is a local Computer shop or computer lab that you could check monitors.

[/quote]If I had the money I would use circular polarized filters on DLP projectors. I tried a setup with dual LCD projectors (this only works on single panel LCD projectors with 45° polarization), but they were poor quality projectors.
You need a silver screen to preserve the polarization. With a good quality DLP you should be able to have a very large screen. DLP needs the bulb replaced every 3,000 hours or so, and it is expensive usually. I am waiting for the ones that have 3 lasers instead of a bulb, that way you don't need to replace bulbs: [url="http://www.novalux.com/display/"]http://www.novalux.com/display/[/url]

If you have a TFT now then you only need one more, if not, I don't know for sure.

I dont have much money at the moment too... Going into the stores to look at the monitors is a good idea....

No, that was a different person. I haven't checked for glass locally.
As far as I know it is just a 2-way mirror with a little less of the reflective stuff on it (or maybe a 2-way mirror would work fine with a little adjustment.)
Don't sweat all the TFT and half-mirror stuff, just grab a standard hand mirror and any two monitors and try this:
[url="http://www.crystalcanyons.net/Pages/TechNotes/DualMonitorDigitalViewing.shtm"]http://www.crystalcanyons.net/Pages/TechNo...talViewing.shtm[/url]
Two CRT's work, one crt and one lcd works. they can even be two different sizes as long as they are close (15" LCD and 17" CRT for example, or 15" CRT and 17" CRT)
The important thing is to get the picture lined up in the mirror. You could even cheat and use the adjustments on the larger screen to make the whole image smaller (look for Horizontal and Vertical size adjustments), and the image on the smaller screen just a little bigger (so some of the info is off the screen.)
Most important, just have fun.
The setup I link to here is kind of a HMD (head mounted display), but on your desktop. This means that you can't move your head or it doesn't work well. The bonus with directly-viewed screens is that you don't have any ghosting at all because each eye is actually looking in a different direction.

Only problem is that you have to use the Tridef software which is far from optimized and is not DX10. Expect a severe drop in framerates. On the other hand, since nvidia refuses to support checkerboarding, you can go with any video card manufacturer out there since the drivers are all third party from tridef (crappy as they are).
