If you have to blame someone, blame the console developers. They're the ones who make shitty ports:
1- Bully PC is one of the worst ports I've ever seen.
2- Resident Evil 4 PC DOESN'T HAVE MOUSE SUPPORT. Fuck Capcom.
As for Dark Messiah and Crysis I don't know, both are supposed to be done well (Crysis at least). Maybe you OS or your drivers are outdated?
