There seems to be a frame rate lag inspite of my high end graphic card (gtx580). Even lowering the game resolution, there was still a lag. Sometimes I need to restart my pc for the game to work smoothly but sometimes, restarting doesn't work. Very annoying. Does anyone know why it happened? and how to fix it? The weird thing is that there was no problem whatsoever with other games and even with this multi player beta game.

This is my system
- intel i7-860
- gtx 580
- 8 gig ram
- driver 267.31 beta version

I used to have this problem (seamed to of fixed it self) but how i would fix it is by going to task manager and closing nvvsvce.exe and NvXDSync.exe hopefully this works for you.

Post back if it works or not

It's not your rig its their software. Try uninstalling the beta drivers and using drive sweeper in safe mode then install the certified drivers and see what happens. I don't know how but I'm lucky enough that my sli 580s don't flicker and so far obliterate it without a challenge. Hope you get it working soon!

I forgot to tell you that the windows I use is Windows7 64 bit sp1. I tried installing older drivers but it still didn't work.

Thnx guys for your replies. I'll try your solution and I'll let you know how it goes.

I couldn't end nvxdsync.exe and nvvsvc.exe. I clicked end process and I couldn't go on from there. There was a pop-up saying The operation could not be completed. Access is denied. Is there other ways to end them?

Crytek staffs are such lazy basterds. They sure took their sweet time to answer people's posts.
