change 3d vision controller to nvidia 770m

Tried Nvidia control panel to use alternate frame rendering for SLI, FXAA, Tripple buffering etc Tried vsync on/off, every form of multisampling, and all graphics options in just about every combination

Checked temperature of both CPU, running between 50-60 C. Checked clock speed of both GPU, they are identical, factory default. Checked PCI-Express power cables to GPU's. Things I've tried so far that did not resolve things I have also tried running Physx on CPU instead of GPU and at first it seamed to have improved things a lot, but after a while I noticed that there were still problems. Disabling SLI fixes the issue, but the game only runs at around 25-30 fps. This causes serious eye strain and makes the game unplayable with 3D vision. The problem gets slightly worse if a crank up the graphics settings, but even on lowest, I still have problem that one GPU is lagging while the other is not lagging at all. But no matter what I try I get perfect FPS on one GPU (left eye in 3D vision) and random serious cutdown on FPS on the other eye as well as stuttering. I've been experimenting with graphics settings from lowest on all to Ultra/High/Media and everything inbetween, all kinds of Multisampling, Vsync on/off etc. Have to set resolution in windows desktop to 1280x720 3D and in game to 1280x768 then alt tab twice to switch to window mode and back to fullscreen to enable 1280x720 with 3D vision in game. Had to run 50Hz instead of 60Hz to get stable FPS.

I'm running the game at 1280x720 with Nvidia 3D vision and 3D glasses on a 3D projector in 50hz. Using the latest Nvidia driver that includes 3D vision and SLI profile for Dirt Rally. I am running two Gigabyte GTX 460 1GB in SLI. I have problem I have been investigating now for several days regarding SLI.
