Loving it! But need a lil help 3d Vision
I recently bought the Acer HN274H 3d monitor, and I have to say it's very nice. 3D looks great in games like BFBC2 and Crysis 2. And in all the games that don't run 3d well / support it, the 120hz is a very sweet alternative.

I got a few questions on tweaking settings to get the best experience.

First, for example, when there is a black object in a bright sky, you can kind of see a doubling of the dark object. Is there any way to fix this or make it less noticeable? In game settings, color management, 3d options in nvidia CP? anything?

Also I have 2x 480 GTXs in SLI, and for the most part 3D runs very very smooth, but occasionally there is a slowdown. Are my 1.5gb videocards hitting a Vram cap? Is it a driver / 3d vision issue? Or do I just need more horsepower (Overclocking the GPUs or buying a 3rd)? I can fit another 480GTX into my rig, but don't want to buy one if it's not going to improve 3d performance. I can get a 590 GTX if it'll be a better 3D vision solution.

I was a little worried dropping $700 on a 27" monitor, but after playing through a few games in 3D I'm really satisfied with my purchase. 3D is a lot of fun. (And I suspect that many of the issues with 3D are due to the fact that many games out were in production / released before 3D was even a real thought) So probably safe to assume that newer titles are going to have 3d in mind as they make them, giving them better compatibility.

Any way, thanks in advance for the help.

Hi, to reduce the double images ('ghosting') you can lower the contrast, but then de image gets darker. A second solution is to use 100hz 3d mode instead of 120hz. The ghosting is significantly reduced in 100hz mode, because the pixels have more time to change. Plus the image is even brighter in 100hz mode than in 120hz. The only disadvantage in 100hz is that the image may flicker a bit, especially during bright scenes. Try it out.

Thank you so much. I'll give it a try and see how it works.

Anyone have an advice on performance? Are 2x 480 GTX as good as it gets? Would I see a noticeable improvement with a 3rd 480gtx? maybe 3GB 590GTX instead?

I personally wouldn't bother with upgrading at this point, 3-way and 4-way SLI performance is very hit or miss with 3D Vision. It took quite awhile for them to fix 4-way SLI performance with 3D Vision but I think they did fix it about a year ago. With Kepler coming in the next 6 months or so, I'm not sure if its worth upgrading to GTX 580s at this point. 3GB probably isn't worth it either at 1080p, if you were running 3D Vision Surround or even Nvidia Surround it might be worth it.

If anything try reducing some of the in-game settings like AA or even shadows. With 3D Vision you don't need those performance expensive options as much as playing in 2D, but keeping frame rates capped to monitor refresh rate is much more important imo.

Well I am running Nvidia 3d, that's why I asked about upgrade :P. 480GTX in SLI runs everything on max settings at max FPS at 1920 x 1080, but when you kick on the 3D, you can feel it. It's still very playable, I just turned off shadows and such in BFBC2, but I was wondering if that's just how 3D vision is, or if it actually is eatting my GPUs hard.

I suppose you answered my question though, I'll just wait to get the 600 series GPUs, maybe they will have the horse power to do max-setting nvidia 3d.

Looking back at your post, what I'm talking about isn't Ghosting. My monitor surprisingly enough doesn't have that problem, not even in 3D (Which is why I got it, a lot of reviews said it was the best monitor for nearly-no ghosting that's out atm) What I was talking about is like an almost double image, just looking at a still dark object near a bright background, you can see a transparent, faint doubling of the image.

But seems I figured out how to deal with it (sort of). The more you crank up the 3D depth in the nvidia stereoscopic options, the further apart the image is. If you keep the 3D at 15-25% the double is very minimal. But if you crank it up to 100% it sticks right out far off from the original object.

So I guess I'll just keep my 3D depth at 25% or less, unless someone else knows a way to keep the depth and make it less visible?

Put the contrast on 0 (on the actual monitor using the buttons). That helps with the ghosting. Make sure to do this when you are in a 3D game. You can also try adjusting the convergence (need to enable advanced hot-keys in the Nvidia panel under Stereo 3d).

Thank you, putting the contrast to 0 helped make the second image a lot less noticeable / gone in some cases. Thank you for that.

I'll play around with the convergence as well, see what I can do with that.

Thanks again, everything looks great now.

Yes I understand you are running 3D Vision, as am I, why else would I be posting my response in this forum? /wink.gif' class='bbc_emoticon' alt=';)' />

But yes 3D Vision effectively cuts your normal FPS in half in non-CPU limited or non-framecapped situations since its rendering each image 2x. Another way to look at it is 3D Vision runs like a single 480 would in your more demanding games and chances are, you have 2x480 because 1x480 simply wasn't enough to get framerates over 60.

To compensate and increase frame rates a bit you can turn down some options like shadows, post-processing, Depth of Field, Blur, anything like that since they can often make the 3D image worst. You can also lower AA to 2-4x MSAA since you get some natural AA from the stereo images composited in your brain. Also, rendering path can make a big difference as well, and dropping down from DX11 to DX9 can make a huge difference in FPS but not much difference in IQ. Metro 2033 and Dragon Age II are two good examples here, although the last few driver releases have improved DA2 performance considerably for me.

But ya I'm hoping Kepler makes a big difference in performance similar to Fermi over Tesla. Going from 2x280 to 2x480 roughly doubled my performance in 3D Vision as expected, and even more than that in a few select games like Assassins Creed II. Adding more GPUs to the mix was more hit or miss in terms of performance and just wasn't worth it to me for the last handful of games I couldn't cap at 60FPS per eye with 2x480s.

Ya Assassin's Creed II runs smooth AND it looks great because you can turn off all the 2D HUD stuff, so all you see is 3D. It's perfect. Same thing with BFBC2 HC mode online, it gets rid of the HUD stuff so you can focus a lot better on the 3D, so it look really good.

As for the FPS thing, I was just curious because, BFBC2 without NV3D runs well over 60fps, but now looking back, even if it's running 90-100fps, 1/2 of that (like running 2 instances of the game) would probably drop me into the 40s and 50s easy, and that's probably why the game feels smooth, until a big explosion or something goes off, or if I zoom in on a target from a high vantage point, it drops my FPS to the 20s / 30s so it feels slow/console ish for a few seconds.

I think i'll wait for the *690* series duel GPU cards and run Quad SLI. Hopefully that'll be enough horse power for 3D vision in BF3. One thing that REALLY bugs me is strategy games. A lot of my RTS games look amazing in 3d.... except the HUD/unit icons are 2d and it makes it so you can't focus your eyes... a real shame too because SupCom2 and Company Of Heroes looks really cool in 3d if you zoom in and don't select any of the units :(. I heard SC2 got around this issue some how, but I don't buy blizzard games so I haven't tested it out myself. Hopefully, other strategy games in the future follow suit with whatever SC2 did to make it work.

Yes I understand you are running 3D Vision, as am I, why else would I be posting my response in this forum? /wink.gif' class='bbc_emoticon' alt=';)' />



But yes 3D Vision effectively cuts your normal FPS in half in non-CPU limited or non-framecapped situations since its rendering each image 2x. Another way to look at it is 3D Vision runs like a single 480 would in your more demanding games and chances are, you have 2x480 because 1x480 simply wasn't enough to get framerates over 60.



To compensate and increase frame rates a bit you can turn down some options like shadows, post-processing, Depth of Field, Blur, anything like that since they can often make the 3D image worst. You can also lower AA to 2-4x MSAA since you get some natural AA from the stereo images composited in your brain. Also, rendering path can make a big difference as well, and dropping down from DX11 to DX9 can make a huge difference in FPS but not much difference in IQ. Metro 2033 and Dragon Age II are two good examples here, although the last few driver releases have improved DA2 performance considerably for me.



But ya I'm hoping Kepler makes a big difference in performance similar to Fermi over Tesla. Going from 2x280 to 2x480 roughly doubled my performance in 3D Vision as expected, and even more than that in a few select games like Assassins Creed II. Adding more GPUs to the mix was more hit or miss in terms of performance and just wasn't worth it to me for the last handful of games I couldn't cap at 60FPS per eye with 2x480s.





Ya Assassin's Creed II runs smooth AND it looks great because you can turn off all the 2D HUD stuff, so all you see is 3D. It's perfect. Same thing with BFBC2 HC mode online, it gets rid of the HUD stuff so you can focus a lot better on the 3D, so it look really good.



As for the FPS thing, I was just curious because, BFBC2 without NV3D runs well over 60fps, but now looking back, even if it's running 90-100fps, 1/2 of that (like running 2 instances of the game) would probably drop me into the 40s and 50s easy, and that's probably why the game feels smooth, until a big explosion or something goes off, or if I zoom in on a target from a high vantage point, it drops my FPS to the 20s / 30s so it feels slow/console ish for a few seconds.
