Sound blaster or other device hogging the bus due to old or bad drivers or sharing IRQs ? Check resources (IRQs) and make sure nothing is shared. Defrag disk ? Is it really only with FSAA ?
I have tried all that, and yes its only with FSAA. Anyway I also have some unstably issues so im returning it.
Good thing I havent sold my GF4Ti4600 yet
Im sure its a great card, tobad its not happy in my rig
