no, it would just need a hack to work on cpu utterly fine, in the same way you can hack vista only games to run on xp. because the ppu is a joke, a fake, and a scam, wooo ppu.
so graw 1 was the first real ppu title. then it turns out the 2nd better, using ppu more graw 2 can run fine with physics ppu stuff run on cpu fine.
either way, can we stop with the threads that seem to be having a go at a company promoting their own company? i'm all for M$ bashing, for the right reasons, not just for the sake of bashing a big company. vista has major issues, networking, explorer is dodgey and there are other problems, but it mostly works fine.
i can't name another company in the history of the world that doesn't try to promote/advertise and sell their new products. have a go at the vista issues, of which gaming performance, and memory usage are not actually issues. nvidia drivers are nvidia's fault, pick on real problems YOU'VE experienced, not heard about then tell me why games for windows or games aimed at vista is bad.
