When I play certain games I get an inconsistent frame rate. My computer is more than capable of handling these games flawlessly, but sometimes the video "jumps" or goes very fast for a short time intermittently. This is very disruptive and interferes with gameplay.
I have a Dual Core AMD 4400+ and a GeForce 7900 GT with a typical 19" LCD monitor. It's hard to do Google searches and such on this topic since it needs a description of sorts. So I've come here seeking some help with this little problem.
Games that this happens on include Chronicles of Rid****, Enclave (these two are both developed by Starbreeze) and today it was the Stubbs the Zombie demo.
Any help or pointers would be greatly appreciated.
Gameplay seems to "fast forward", what could this be?
