Win7 64bit + SLI = pereodic freezes (Crysis)

Hello  
Have you tried patching the game ?
Also try a different driver(even some older ones)and check how it performs.

I have a very similar problem but I am only running one GTX 260 - http://www.tomshardware.com/forum/279764-33-build-graph...

The mouse/video freezes yet the game play still goes on. If I turn graphics settings to medium there is no problem but I did not just build a new computer to run a 2year old game on 'medium'  

I'm experiencing a similar problem with 2 8800GT's in SLI. I've found that running the game in a window resolves the issue. When I boot up the game proper from a save file, I can then change to fullscreen without any problems. The issue only occurs in SLI, and seems to coincide with the installation of the 196.21 drivers.

I do, however, experiencing periodic freezing during gameplay, but I think that's a separate issue.

Has anyone tried downgrading to an older driver? The 196.21 gave me massive problems. Downgrading to 190.62 fixed everything for me.

After doing some basic searching, it seems SLI in general (without tweaking anything) can cause problems in older games and really only improves performance in a select few games anyways.

Hi,
I am having the same problem with just one 8800gt, in WOW. Frame rate is less than half when I had i running in XP. See my info in this form

Did you by chance add another periferal, or change your mouse or keyboard out for one that is wireless or backlit?

I had your exact problem a couple weeks ago, and it turned out the new keyboard I bought drew too much power, and as a result it would get uninstalled by windows. I also had the same issue when using a KVM switch with just my mouse (sidewinder x8). The mouse would uninstall, making it not work for 5-10 seconds, then it would be recognized by windows again, and reinstall.

I eventually found that my keyboard, which draw too much power, had to go. I replaced it with my older keyboard and all issues stopped.

This problem only happened in one game routinely, due to the extra strain the game put on my machine, which could explain why it only happens in crysis.
