To get to the point, when I play Crysis there is major mouse delay with vsync turned on, a little better but not much when its off.
Vsync on or off, the game still runs like its being played on windows98 - lag/low fps...
sometimes the game will studder as if it is freezing...
Also when I put the game in windowed mode, it has a significant raise in fps from fullscreen. Still though, its not high fps..
Someone please help...
I am running:
Windows 7 64 bit
i7 950 @3.2 ghz
And I'm using a Toshiba LCD around 40 inches, 60 Hz
^^ I have a feeling that might be the problem
One more side note...
I just recently bought the other gtx570 for sli, and after hooking up I played bf3, and there's this weird studdering kind of often when playing, even though the fps are high... I'm 99.99% I hooked everything up right, and enabled sli.
Do you still get the problem if you set your cpu to stock speed?
I had a similar issue which was solved by lowering my ram speed. Sli can be tricky to get working in my experience, try downloading a gpu monitoring tool (i use evga precision) to check both cards are getting balanced usage.
I had bad tearing problems playing Just Cause 2 with Sli, set Nvidia control panel to single display performance mode, it fixed the problem.
