It's not possible Ea and Crytek haven't fixed the 3d problem since last year the game was relased .

I have a win 7 64 bit operating system and a gtx 690 ( drivers updated 2 week ago )
Note I have to uncheck the "multigpu-option" in the nvidia panel to run the game !!!!!!
In game library options dx11 .
If the "nvidia 3d vision" is enabled ( through the "nvdia control panel" ) , the game crashes istantly when i launch it .
If the game is 2d , all is ok .

I tried to use the the dx9 as graphics library in the "game setting".
I can execute the game in "3d vision mode" ( woooww ) but once i play the game the 3d glasses shows me images not coordinated ( in the left eye images are darker and the right are clearer !!!!! )

I use 3d for all game i play .

THIS IS THE UNIQUE GAME THAT GIVES ME PROBLEMS .
Please advice

has anyone got the question ?
thank

ok . solved .
I had to uncheck the fxaa graphic option related to "crysis 2 . exe" in the "nvidia control panel" .
to Close

However 3d quality is not good with this game .
Hope with Crysis 3 there'll be some improvements
