As i stated in the "Driver updates" post i'll be posting critical and vital drivers seperately starting from this post. As usual drivers for nVidia are regularly being released, however, ati managed to squeeze out a critical driver update with it's 7.12 catalyst driver, accompaning these imporatnt release notes and highlights. Thus, you can always try them out to check their hit on Crysis! One more point I'd to add is that it contains fixes for other games such as Lost Planet, HellGate, STALKER, COD, and many more; again refer to the release notes at the bottom of the post for details:
