Re: cant run 64bit crysis???
there was a thread about this a while back when it was released.
if i remember it had something to do with SLI profiles (regardless whether your using it or not)....or i could be blatantly wrong.
tbh just google it
EDIT: OP state your operating system, as it will yield more results
if you have vista 64:
