I can't seem to get Mass Effect to run with any of the newer 177.xx drivers. I've tried 177.39, 177.79, and the new 177.83 WHQLs with no luck. 175.19 work fine, but anything else and I get a GPF right after launching the game. Is anyone else having problems? Any tips would be greatly appreciated. I'm okay with sticking with the 175.19s but I'd really like to take advantage of the new PhysX drivers.
