The problem is kinda hard to describe so I'll try my best... The problem is most prevalent in all source engine games (Half-Life 2, Sin Episodes, CSS etc) although it seems to effect a few other games, just not as badly.
It isn't a normal type of stutter in that the frame rate will drop very low for a short period of time as my frame rate is always stable. Instead I only get the effect when I move the character accross the screen, then it all becomes very juddery like the character is walking through mud or something and freezes with every step. When not moving in the game world, everything is fine.
Another characteristic of this problem is that it gradually gets worse with time but dissappears for a while after a reboot of my computer.
Once I get into the game after a reboot, everything will be completely smooth. However, through a time of about 40 minutes it will get worse and worse, until at the 40 minute mark it becomes pretty unplayable when trying to move at all and forcing me to reboot to get smooth performance again.
I'm pretty sure my computer is free of any spyware or viruses.
I cannot remember exactly how long I've had this problem for but its been quite a while now.
