I recently built a new rig with an E6400, 2GB Ballistix DDR2-800, Asus P5K Deluxe, EVGA 7900GS, etc. It runs Company of Heroes, Call of Duty 2, and Medieval Total War II perfectly however when I play CS:S, every 20-30 seconds the game seems to freeze for a second or two and then resumes like normal. My ping is usually at around 30-60 depending on the server and I run everything on high except for 2x AA and at 1680x1050. Does anyone have any ideas why my game is doing this?
