i recently had a geforce 4200 ti 128mb and played counter-strike with always getting 100+ fps. i just bought a geforce 6800 gt 265mb so i could play doom3 and painkiller better. what gets me is that when i play cs with my new card, my fps drops to around 40 and stays there, and every now and then bumps up to 100+. this is really irritating and makes no sense to me. can anyone help me?
