I've been running Magic Bullet Looks in After Effects without issue. But when Battlefield Bad Company 2 recommended I updated my drivers, Magic Bullet stopped working, saying that "It was unable to initialize in 64 bit mode"
My question, is will 64 bit Vista supprt 32 bit drivers for the GTX 285, so that I can get back performance in After Effects?

No - You may not run 32 bit drivers on 64 bit windows.
