Geforce GTX 480 works with 3d vision
 

...All of a sudden i updated drivers to 344.11 and now its in stereo

What kind of stereo? Are you saying that quad buffering is enabled?

i cant see it saying QUAD buffer in the Nvidia control panel, but its stereo allright..and powering my Nvidia glasses

... i have viz.go(viz.FULLSCREEN |viz.QUAD_BUFFER) in my script so i guess Vizard trumps Nvidia control panel??

Can anyone else verify?

I'm going to speculate about some restrictions:

1) the graphics card you're trying use for quad buffering should only have 1 display on it

2) that display should run at 120 hertz

I would like to try this out, but my rig has a complicated multi-monitor setup on it right now, and to break it down and set it back up is a pain.

Oh, and I should say that I believe there are differences between what NVidea's 3D Vision system is doing and typical quad buffering. So, this may work just for 3D Vision.

Ok so i had to move my office around. Everything go unplugged and replugged. Stereo stopped working. After fiddling with various settings, i fixed it by disabling SLI, Applying. Then re-enabling, Appying.
So its stereo and in SLI mode. However i only have 1 stereo display to test with.

No luck on this end
 

No luck! The machine I tried this out on has a GTX 790 and 690 installed. Vizard reports that neither card supports quad buffering.

Hey bruno, any chance that you had the Nvidia 3D Vision plugged in while you did this?
