Okay I fired up Crysis 2 tonight to check FPS and GPU load (note I have QUAD SLI disabled) and low and behold I notice that only one gpu is actually active out of the four. I should have two GPU's working on the GTX 295 w/driver 267.24.
I noticed when Andrew was playing Crysis 2 on the GTX 590 that he was playing with 3D Vision Surround (3 monitors). Did you have both GPU's active in game?

So we must hand it over to our tame PC tweaker. Some say he sticky tapes a block of uranium to his dinner before eating it and that he sucks moisture out of ducks. All we know is, he's called Hooks.
I also can confirm that Driver 267.24 with EVGA SLI Enhancement 38 supports the 200 series, 3 Way SLI scaling is great [img]http://forums.nvidia.com/public/style_emoticons/default/w00twave.gif[/img] [img]http://i1004.photobucket.com/albums/af162/jessemitchell25/Crysis2Demo_2011_03_09_00_58_04_165.jpg[/img]
Okay I know what's going on here now, and this is not going to apply to you guys that have Single GPU Cards. I knew that SLI works on my setup and will run fine in 2D (QUAD SLI) in Crysis 2, but there is an issue with DX9 games and QUAD SLI and 3D Vision so I have to disable QUAD SLI for it to work correctly in DX9 games. The problem is that when I disable SLI in the Nvidia Control panel for my pair of GTX 295s, it completely disables ALSO multi-gpu on the top card too, so when I run a game I'm basically trotting a long with a single GPU, a GTX 275 GPU. If one, has a pair of multigpu cards, one is not given the option in the Nvidia Control Panel of running QUAD-SLI, MULTIGPU, or a Single GPU. One either is going to be running all 4 or only 1 (there is also another way of getting 3 gpus by forcing one to physx but I'll leave that out for the moment), but not in between. You can go and monkey with Inspector and force a game to run with only two gpu's etc, but I'm just talking about the Nvidia Control Panel and how it works for now. Basically I'm stuck playing Crysis 2 in 3D Vision with a GTX 275 equivalent, UNLESS I do the following...
What I had to do to get around this was go into Device manager and just completely disable the bottom GTX 295 (its pair of GPUs). Finally, the Nvidia Control Panel gave me the option of running the top GTX 295 in multigpu mode (or diable multigpu mode). However, even with multigpu mode on I'm getting the same framerate as with a single GPU . With a single GPU I'm getting around 98% utilization per EVGA Precision, and with multigpu mode (2 GPUs of the GTX 295) I'm getting 51% on each GPU. SLI visual indicators also come on with multigpu mode, and with 3D Vision the green bar is about two inches long. Tap Ctrl+T, and the GPUs jump up to where they should be. So now with Crysis 2 we see three sets of problems for a Quad SLI setup on the 200 series amd 3D Vision: 1) Quad SLI must be disabled to run Crysis 2, 2) Disabling SLI in Nvidia Control Panel reduces you down to 1 GPU, not 2 GPUs, 3) However, disabling the bottom card completely in Device Manager gives you the option of running the Top GTX 295 in multigpu mode in the Nvidia Control Panel, but it's scaling and performance is identical to a single gpu. Oh and I'm getting about ~21-35 frames per second in Crysis 2 with 3D Vision enabled, regardless of single or multigpu mode.
So here's my question for Andrew when he decides to come read this post: How does your scaling look in Crysis 2 with the a single GTX 590 card in 3D Vision? Is it scaling the same as the GTX 295 (where I get around 50-52% for GPU1 and GPU2, and with a single GPU I get 98-100%)? If you are getting similar results, why? And if not, why is the GTX 295 suffering from this and not the GTX 590?
So I fired up a couple of other DX9 games to see if my findings here were equivalent, with the same setup as my last Crysis 2 effort: my bottom GTX 295 card diabled in device manager and running the Top GTX 295 in multigpu mode. Turned on Precision so I could see that GPU1 and GPU2 were there. I tried Call of Duty Black Ops with 3D Vision enabled, GPU1 and GPU2 were at full bore 98% and about 52 frames/sec. Next I tried Fear 2 Project Origin with 3D Vision enabled, GPU1 and GPU2 were at 78% and the frame rate was maxed at 60 frames/sec (remember vsync is on 3D Vision), so the scaling there in FEAR 2 makes sense, since it can't push the frame rate beyond that 60 limit.
The other little oddity here is that COD Black Ops and FEAR 2 do NOT kick on the multigpu/SLI Visual Indicator with 3D Vision enabled (at least not on a GTX 295 setup), but it DOES come on with 3D Vision disabled IN the Nvidia Control Panel (not the Ctrl-T toggle). This has been pretty much my standard witness of DX9 games on my system since the 256 drivers, so no surprise. In Crysis 2, the SLI Visual Indicator comes on regardless if 3D Vision is on or off (both Nvidia Control Panel toggle or the CTRL-T toggle).
Nvidia, it looks like you have a bug here with GTX 295 in Crysis 2 and 3D Vision, not only QUAD SLI (which we all already knew), but also standard multigpu mode of a single GTX 295 card. And if one does have two multigpu cards, it would help to put an option in the Control Planel that when you disable SLI, you still have the option of running the top card in multigpu mode. The way it works now is that when you disable SLI it reduces you down to one gpu. That's not good. I shouldn't have to go to Device Manager to disable the bottom card just to bring back multigpu card for the top card.
I think I have met my all time high of frustration with these GTX 295s, we are now in a love-hate relationship with 3D Vision.

It also might be helpful if you gentleman that posted above (or anyone else for that matter) that are running a SLI rig, either standard SLI or 3-way SLI with single gpu cards, to run Crysis 2 in 3D Vision. I noticed that you posted 2D results, and I'd like to see your 3D results as my issues are always in 3D and never in 2D (I plow right through any game with you in 2D with QUAD-SLI). I'd like to see the results (fps and gpu scaling) with both 200 series cards on one and hand and 400/500 series cards on the other. I need to find out if the problem persists in some different combinations:
1) Is the problem unique to any series multigpu cards only?
2) Is the problem unique to pre 500 series multigpu cards only (GTX 295, 9800GX2, etc.)?
3) Is the probem unique to 200 series cards and not 500 series cards in whatever combination of SLI?
4) Or, finally, is the issue present in ANY combination of SLI for ANY series?
Remember, the context for 1-4 above is 3D Vision, not 2D. The more corroborative data I have on the problem, the easier it'll be for Nvidia to actually implement some kind of fix.

We will see. As I referred in the posts above, the issue is not SLI or multigpu in 2D mode, but SLI and multigpu mode in 3D Vision. But I will definitely give this a shot and see if it behaves any different.
It'd be nice to see some results from you guys though IN 3D.

wow thanks a lot for that EVGA SLI Enhancement!
i can finally use both my cards and play at 120fps with all maxed out
gonna try this in 3d and dragon age 2
it works perfect.. gives me 60fps per eye in crysis 2
for dragon age 2 it still sucks 32fps with max settings dx11
and in 3d like 15fps.... i get better with just 1 card enabled.. 35fps lol
i am really happy about that sli enhancement.. it made all my other games run at its max!
IMHO i was using only 1 gpu for the past 7 months or more... i had the other gtx 480 for physics lol
i can finally leave it with sli enabled :)

Thanks. This is exactly what I'm looking for.
So SLI GTX 480 gets the nod. I'm sure GTX 580/570 standard SLI will be the same.
Now, I need to see GTX 480/580 3-way SLI and GTX 260/285 3-way SLI. I want to know GPU% and FPS.
After work today, I will try the EVGA SLI enhancement and post my own findings with a single GTX 295 (I highly doubt it'll fix my QUAD SLI problem and 3D Vision) and see if I can get to an acceptable frame rate and proper scaling.

yea man give it a try am gonna keep on testing more games , just tried resident evil 5 60fps per eye i really don't like 3d in this monitor..

Hey, the cool thing (in all sarcasm) is that you dont even need 2 GPUs to run Crysis2 on max lol even in 3D. My 570 runs in 3D usually getting 60+fps
[/quote]
Steiner,
In all sarcasm, it would also be helpful if you would read what I wrote too. As I noted, when I switch off SLI in the Nvidia control panel, it also disables multigpu on my GTX 295. Guess what a GTX 295 is under the hood with one GPU? A GTX 275 (with different clocks). Guess what frames per second I'm getting in Crysis 2 with 3D Vision with just one of those GPUs? About half of what you are getting, which is about right, a GTX 570 is roughly twice the speed of a GTX 275. So no, if one does have a 200 series card and wants to play in 3D, they will need 2 gpus to get 60 frames per eye in Crysis 2.
When I was able to get my single GTX 295 card in multigpu mode in Nvidia control panel, thus enabling both GTX 275 GPUs onboard (which should be roughly equivalent to your 570), by disabling the bottom GTX 295 card in device manager, I was still getting the same framerate as a single GPU because both the GPUs were operating at ~50%. I have yet to try the EVGA SLI patch that was posted earlier, though my rig already works fine in SLI with Crysis 2 as is in either multigpu mode or QUAD SLI while running the game IN 2D. So either its a driver problem for multigpu mode and 3D Vision or can be fixed with profiles...or something else...
Either way, what you posted wasn't helpful even if you thought it was cute, I already realize that GTX 480/470/580/570 single gpu's won't have a problem with this game in 3D with a single GPU application. I'm trying to find the principled reason of the degraded SLI issue in 3D Vision with this game. Since I'm on a 200 series card, it'd be nice if I can take advantage of what I have to run the game acceptably. I have 4 GPUs, collectively a lot of power, but can only tap one of them effectively to run Crysis 2.

I tried EVGA's SLI enhancement patch. Same results, no change in 3D Vision multigpu mode. 2D runs great and going back and forth with the Ctrl-T toggle of turning off 3D Vision fills the SLI indicator bar nicely for 2D, horrible in 3D, down to about a centimeter.
Looks like a driver issue that can't be fixed with a profile for the GTX 295.

Posted by Rsabatino, techjesse you are the people's champ of overclocking
What I had to do to get around this was go into Device manager and just completely disable the bottom GTX 295 (its pair of GPUs). Finally, the Nvidia Control Panel gave me the option of running the top GTX 295 in multigpu mode (or diable multigpu mode). However, even with multigpu mode on I'm getting the same framerate as with a single GPU . With a single GPU I'm getting around 98% utilization per EVGA Precision, and with multigpu mode (2 GPUs of the GTX 295) I'm getting 51% on each GPU. SLI visual indicators also come on with multigpu mode, and with 3D Vision the green bar is about two inches long. Tap Ctrl+T, and the GPUs jump up to where they should be. So now with Crysis 2 we see three sets of problems for a Quad SLI setup on the 200 series amd 3D Vision: 1) Quad SLI must be disabled to run Crysis 2, 2) Disabling SLI in Nvidia Control Panel reduces you down to 1 GPU, not 2 GPUs, 3) However, disabling the bottom card completely in Device Manager gives you the option of running the Top GTX 295 in multigpu mode in the Nvidia Control Panel, but it's scaling and performance is identical to a single gpu. Oh and I'm getting about ~21-35 frames per second in Crysis 2 with 3D Vision enabled, regardless of single or multigpu mode.
So here's my question for Andrew when he decides to come read this post: How does your scaling look in Crysis 2 with the a single GTX 590 card in 3D Vision? Is it scaling the same as the GTX 295 (where I get around 50-52% for GPU1 and GPU2, and with a single GPU I get 98-100%)? If you are getting similar results, why? And if not, why is the GTX 295 suffering from this and not the GTX 590?
So I fired up a couple of other DX9 games to see if my findings here were equivalent, with the same setup as my last Crysis 2 effort: my bottom GTX 295 card diabled in device manager and running the Top GTX 295 in multigpu mode. Turned on Precision so I could see that GPU1 and GPU2 were there. I tried Call of Duty Black Ops with 3D Vision enabled, GPU1 and GPU2 were at full bore 98% and about 52 frames/sec. Next I tried Fear 2 Project Origin with 3D Vision enabled, GPU1 and GPU2 were at 78% and the frame rate was maxed at 60 frames/sec (remember vsync is on 3D Vision), so the scaling there in FEAR 2 makes sense, since it can't push the frame rate beyond that 60 limit.
The other little oddity here is that COD Black Ops and FEAR 2 do NOT kick on the multigpu/SLI Visual Indicator with 3D Vision enabled (at least not on a GTX 295 setup), but it DOES come on with 3D Vision disabled IN the Nvidia Control Panel (not the Ctrl-T toggle). This has been pretty much my standard witness of DX9 games on my system since the 256 drivers, so no surprise. In Crysis 2, the SLI Visual Indicator comes on regardless if 3D Vision is on or off (both Nvidia Control Panel toggle or the CTRL-T toggle).
Nvidia, it looks like you have a bug here with GTX 295 in Crysis 2 and 3D Vision, not only QUAD SLI (which we all already knew), but also standard multigpu mode of a single GTX 295 card. And if one does have two multigpu cards, it would help to put an option in the Control Planel that when you disable SLI, you still have the option of running the top card in multigpu mode. The way it works now is that when you disable SLI it reduces you down to one gpu. That's not good. I shouldn't have to go to Device Manager to disable the bottom card just to bring back multigpu card for the top card.
I think I have met my all time high of frustration with these GTX 295s, we are now in a love-hate relationship with 3D Vision.
What I had to do to get around this was go into Device manager and just completely disable the bottom GTX 295 (its pair of GPUs). Finally, the Nvidia Control Panel gave me the option of running the top GTX 295 in multigpu mode (or diable multigpu mode). However, even with multigpu mode on I'm getting the same framerate as with a single GPU . With a single GPU I'm getting around 98% utilization per EVGA Precision, and with multigpu mode (2 GPUs of the GTX 295) I'm getting 51% on each GPU. SLI visual indicators also come on with multigpu mode, and with 3D Vision the green bar is about two inches long. Tap Ctrl+T, and the GPUs jump up to where they should be. So now with Crysis 2 we see three sets of problems for a Quad SLI setup on the 200 series amd 3D Vision: 1) Quad SLI must be disabled to run Crysis 2, 2) Disabling SLI in Nvidia Control Panel reduces you down to 1 GPU, not 2 GPUs, 3) However, disabling the bottom card completely in Device Manager gives you the option of running the Top GTX 295 in multigpu mode in the Nvidia Control Panel, but it's scaling and performance is identical to a single gpu. Oh and I'm getting about ~21-35 frames per second in Crysis 2 with 3D Vision enabled, regardless of single or multigpu mode.

1) Is the problem unique to any series multigpu cards only?
2) Is the problem unique to pre 500 series multigpu cards only (GTX 295, 9800GX2, etc.)?
3) Is the probem unique to 200 series cards and not 500 series cards in whatever combination of SLI?
4) Or, finally, is the issue present in ANY combination of SLI for ANY series?
Remember, the context for 1-4 above is 3D Vision, not 2D. The more corroborative data I have on the problem, the easier it'll be for Nvidia to actually implement some kind of fix.

I also can confirm that Driver 267.24 with EVGA SLI Enhancement 38 supports the 200 series, 3 Way SLI scaling is great [img]http://forums.nvidia.com/public/style_emoticons/default/w00twave.gif[/img]

[quote]I have a single dual GPU card (7950GX2, 9800GX2, GTX 295) should I use this enhancement?
Yes, this enhancement will benefit dual GPU cards as well.[/quote]
We will see. As I referred in the posts above, the issue is not SLI or multigpu in 2D mode, but SLI and multigpu mode in 3D Vision. But I will definitely give this a shot and see if it behaves any different.
It'd be nice to see some results from you guys though IN 3D.

i can finally use both my cards and play at 120fps with all maxed out
gonna try this in 3d and dragon age 2
it works perfect.. gives me 60fps per eye in crysis 2
for dragon age 2 it still sucks 32fps with max settings dx11
and in 3d like 15fps.... i get better with just 1 card enabled.. 35fps lol
i am really happy about that sli enhancement.. it made all my other games run at its max!
IMHO i was using only 1 gpu for the past 7 months or more... i had the other gtx 480 for physics lol
i can finally leave it with sli enabled :)

Thanks. This is exactly what I'm looking for.
So SLI GTX 480 gets the nod. I'm sure GTX 580/570 standard SLI will be the same.
Now, I need to see GTX 480/580 3-way SLI and GTX 260/285 3-way SLI. I want to know GPU% and FPS.
After work today, I will try the EVGA SLI enhancement and post my own findings with a single GTX 295 (I highly doubt it'll fix my QUAD SLI problem and 3D Vision) and see if I can get to an acceptable frame rate and proper scaling.

too much ghosting , there's nothing like the DLP tech. NO ghosting!

Hey, the cool thing (in all sarcasm) is that you dont even need 2 GPUs to run Crysis2 on max lol even in 3D. My 570 runs in 3D usually getting 60+fps
[/quote]
Steiner,
In all sarcasm, it would also be helpful if you would read what I wrote too. As I noted, when I switch off SLI in the Nvidia control panel, it also disables multigpu on my GTX 295. Guess what a GTX 295 is under the hood with one GPU? A GTX 275 (with different clocks). Guess what frames per second I'm getting in Crysis 2 with 3D Vision with just one of those GPUs? About half of what you are getting, which is about right, a GTX 570 is roughly twice the speed of a GTX 275. So no, if one does have a 200 series card and wants to play in 3D, they will need 2 gpus to get 60 frames per eye in Crysis 2.
When I was able to get my single GTX 295 card in multigpu mode in Nvidia control panel, thus enabling both GTX 275 GPUs onboard (which should be roughly equivalent to your 570), by disabling the bottom GTX 295 card in device manager, I was still getting the same framerate as a single GPU because both the GPUs were operating at ~50%. I have yet to try the EVGA SLI patch that was posted earlier, though my rig already works fine in SLI with Crysis 2 as is in either multigpu mode or QUAD SLI while running the game IN 2D. So either its a driver problem for multigpu mode and 3D Vision or can be fixed with profiles...or something else...
Either way, what you posted wasn't helpful even if you thought it was cute, I already realize that GTX 480/470/580/570 single gpu's won't have a problem with this game in 3D with a single GPU application. I'm trying to find the principled reason of the degraded SLI issue in 3D Vision with this game. Since I'm on a 200 series card, it'd be nice if I can take advantage of what I have to run the game acceptably. I have 4 GPUs, collectively a lot of power, but can only tap one of them effectively to run Crysis 2.

Looks like a driver issue that can't be fixed with a profile for the GTX 295.
