Also can confirm that one Raid Mode stage in the snow from RE6 that used to lag me and I know many others back also now runs pretty smoothly (not perfect 60fps, but ran 40-50 fps, which is better than the previous 15-25 it supported).
Not all issues are fixed though, game still has that stuttering when loading issue for me, the thing where when it first loads an area the game has some freezes for the first 5 - 15 seconds. But, progress!
Edit: The stuttering may be amplified by me rendering out two videos in Sony Vegas, will test again when no longer having my computers CPU being consumed by that. XD;
