gtx 460 sli in 3d vision
hi,

i was very excited when i first played in 3d vision on my toshiba 3d laptop so i decided to go for a full desktop rig to make no compromise between quality and performance :
i7-940 (stock speed no overclock)on intel dx58og board
2x gtx 460 in sli (palit 1gb sonic edition - no oc 700mhz core default)
windows 7 64-bit with latest 280.26 nvidia drivers
all my games are on steam (so up-to-date) and I'm running them in 3D vision @1026x768 120 Hz which is the native res of my Viewsonic projector.
My settings are all default Nvidia ones except for Power Management (Best Performance) which i set to Best Peformance under windows too.I set the SLI setup to maximize 3d performance.

The games I really enjoy with no compromise:
Burnout Paradise, Batman AA, Tomb Raider Underworld, COD Black ops, BFBC2 in high settings

The games I have trouble with:
- Racer GRID : every 10 to 20s the game freezes for about 1s which is very distracting. i tried everything : lowering settings, vsync/triple buffering tweaks, the alt-tab trick posted in some forums (exit/reenter game)...nothing worked

- Just Cause 2 : i get very annoying screen tearing when looking around which is a shame with my config right? i turned of AA and tried to turn off motion blur (slight improvement but still tearing), played with vsync/triple buffering..no effect...lowering effects brick by brick improves the tearing but i have to set everything to low or off to get a confortable experience...isn't it crazy? i think it worked better at the same res on my 3D laptop will a single GTS 35oM!

- Portal 2 : everything set to high, vsync on gives me weird tearing again looking at some floors/objects..yet again i can feel some improvements when lowering the settings..but isn't it crazy?...it is said to run close to 100 fps with a single card and no 3d vision..shouldn't 460 sli be enough to support 3d vision with high settings on this?

i hope you can help me fix these issues...i'm a real fan of 3d vision overall but i find it difficult to get the perfect tweaking for each game..why don't you post optimal playable settings in sli under 3d vision on your web site? it would make the job much easier!

thx and regards!

ok so for any one interested :

- portal 2 : just set sli settings to single gpu for this game. one gtx 460 is able to manage high settings in 3d vision @ 1024*768, SLI is responsible for the tearing/stuttering.

- just cause 2: i played a lot with settings to find the best compromise i could but yet i cannot understand how 2 gtx 460 cannot handle this game in 3D vision @1024*768 full settings, i really think the sli 3d vision profile can be improved through driver optimization...so best config i found to have smooth gameplay(no tearing/stuttering) : set sli to alternate frame rendering 2 for this game. no AA, disable gpu water simulation & high res shadow,set shadows to low and ssao to medium...everything else to high (not ultra high).

hope this helps some of you. i really think nvidia could really improve experience of pc users by extending its geforce website optimal settings section to SLI / 3D vision configs.

i'm curious about your optimal settings out there in 3D vision SLI configs guys for just cause 2..do you also find the "alternate frame rendering 2" sli profile to perform better than the default nvidia one ? do you experience tearing/stuttering in crowded place like towns, flower fields when looking around with highest settings ? if yes what are the settings you lower to get the best quality/smoothness compromise ?

thx!

Do you have the SLI bridge installed between the two cards? It's a small connector that goes on top of the two cards to physically connect them together. It's possible to do SLI without the bridge but you get terrible performance, wondering if this is your issue?

Just Cause 2 is one of those titles that never ran quite as well as you would expect it to relative to single GPU performance with 3D Vision and SLI performance with 3D Vision off. Basically, the 2nd GPU adds very little performance while in 3D Vision. I messed with all of those AFR/SLI flags about a year ago and waited through 3-4 months of driver releases and they never really improved performance much. I haven't gone back and tested any of the newer drivers but I doubt they've improved JC2 performance too much since then.

The single biggest boost in performance however will be to turn off CUDA water, as that can use anywhere from 15-30% of a single GTX 480's GPU cycles. Last I checked, CUDA processing can only run on a single GPU in SLI, so this in turn reduces the amount of processing available for rendering. Basically, if CUDA water requires 30% of a single GPU's time, both GPUs will be reduced to 70% for rendering graphics. This may also help smooth gameplay out for you a bit; even though Fermi allows for execution of multiple kernels concurrently, context switching on the same GPU still requires a good bit of overhead and loss of efficiency.

Downside of turning off CUDA water is you lose some pretty water effects when you're actually near the water, but the CUDA effects are always processing so they actually drop your performance 100% of the time even when you're nowhere near the water.

thank you very much for your extended reply. i'm happy to see i'm not the only to have these issues. i hope it will get fixed in further driver releases...(any nvidia guy out there to confirm we may still hope for a fix?)

about the bridge yes it is connected and the performance issue is only related to just cause 2 so i guess my sli setup is not a problem here as i've seen huge performance improvements in other games in 3D vision.
