Well i just played bf1942dc for a while, no vpu errors.
I had that error with sp2, so i wiped my drive and no sp2 right now, i had tried all the cat drivers, from 3.7-4.9, with fastwrite off. I went back and cleaned everything ati off my pc, and went back to cat 3.7, i have heard it works better with older cards. I installed 4.9, i wasnt impressed.
Oh well, we'll see what happens.
