I have ATI radeon 9250 with the last driver. When i run CS i get full FPS and no freeze. After 5min of gaming (online or LAN) it start to spike and freeze. Looks like my PC is doing something... I look to my task manager while i was gaming online i see that my cstrike.exe has 0-1 usage, and SYSTEM had 40 and Idle system Process 50-80.. anyone knows why my computer lags on this very old game? only occrus with CS...
