I know this problem has been addressed but i wanted to know what progress has been made on the problem. It seems for me that when i have a "cold start" so to say with my game and i move around it will stutter really bad and wont stop....1 fram every 4 seconds.... i have an ATI x800 pro with CATALYST 6.4 installed on my pc. 6.5s aren't any better. please let me know if there are any settings on my console in HL2 that i can tweak that may help. thanks!
