I just noticed sth strange. I have a mbp late 2011, 8gb ram, 512ati6750. I just installed diablo 3 and tried to play. It runs smooth but every time i open a new area while running or enemies appear, i get a small stutter. I have tried everything like low fx, lower resolutions and everything turned to the lowest setting but the stutter remains. Then, i used the gfxstatus, forced intergraded (hd3000), texture set to High, resolution (1440X900) and everything else to lowest setting. This time no stutter at all and smoother... Any suggestion? I tried cinebench and measured ati to 39fps.
