I have this recurring problem. The first time it happened to me, I was doing a time demo and I noticed it was going very slow. My frame rate was in the teens. I had to do a system restore in order to get it back to 40-50 fps. Now it seems to be doing it more often and I have to do a system restore every day. Last night I was playing Doom and it was just flying, no problems at all. Today, I loaded it, and it was jumpy as hell. Once I noticed it was jumpy, I looked for Load Warnings, and these are the two I found:
WARNING: Couldn't load image: _emptyname
WARNING: Couldn't load sound 'guisounds.wav' using default
I've already tried several different Forceware drivers and uninstalling and reinstalling the game. Can anyone tell me.... What's Going On ?!?!?!?!?!?!
