COD 4 problem!
i just bought call of duty 4, installed it, went in its options and set it to optimal system settings, it set the resolution to 800x600, which was running fine, i have a nvidea geforce 7600, pc is 3.4 Ghz and 2 gb of ram, and enough free space as well, which was all enough for this game, but what started happening after some time i had played the game, it started lagging, ( dont know if this is what it's called) like the fps rate has come down a lot or something, then it started running smooth again, now whenever i start the game, after some 10 mins this thing starts happening, afterwards it just runs smooth for 5 mins, and then lags for 2 mins, this keeps on happening forever. . .
any ideas ?. . . . .
