Strange performance issue

**MattF** · 09-08-2010, 08:56 AM

I'm getting strange low framerates at seemingly random times. I'll be wandering around a room at perfect 60fps, and the game will decide to start running at about 20fps until I quit and restart. To be clear, absolutely NOTHING is changing graphically when this happens, so its not simply my computer being unable to handle the load. Once the low fps starts I can return to an area that was running perfectly before and the low fps continue.

This also didn't happen at all in the demo using the same graphics settings, and no, I'm not mistaking the insanity effects for a low framerate (checked with fraps just to be sure).

System specs:

Intel core2duo at 3.0ghz
Nvidia GeForce GTS 250 1GB
2GB ram
Windows 7

Game settings:
'High' chosen in 'General' tab of launcher.
1920x1080 resolution.
