Default Re: GTX 285 + GeForce Vision

You do understand that you just proved my point with that screenshot. That is 4 Way SFR. = Non Optimal SLI Rendering. SLI uses AFR solutions these days. SFR will always slow your framerates down to that of a single GPU due to the way games are rendered these days.

Yes you can have Stereoscopic drivers enabled using Quad SLI. But it comes with this penalty.

1) No control of your SLI profiles. All games will run in 4 way SFR ((= Dog performance in 90% of games))

2) Split Frame Rendering: No AFR. No accelerated performance of Quad SLI.

3) Games will not use NVidia's prebuilt SLI Rendering profiles.


So no. Quad SLI and Geforce 3D Vision do not work together. The fact that you can enable them together does not mean they function correctly. If you are using Quad SLI with 3D Vision. You will be getting the performance of a single GTX 275 in all your apps 95% of the time. You are far better off taking out your second GTX 295 if you want to use 3D Vision because AFR and profiles work properly. It appears to work but the reality is it doesnt. Nvidia even states that Quad Sli and 3 Way SLI are currently unspported.. It is unfortunate you did not know ahead of time. However they are going to eventually support 3 way and quad SLI properly.
