This is a regression. THe fan only goes up to 3-4K RPM and stays there: it throttles because it cannot dissipate the heat fast enough. Thus I only get around 45fps and a lot of jitter and stutter.
With Patch 6 the fans would go all the way 5K+ RPM (much louder) but the game would also stabilize at 60fps even in Act 3. Somehow with Patch 7 it cannot trigger the fans to go higher. Note that by default all MBPs are NOT in High Power Mode. You need to enable it otherwise the fans never reach that high. For both Patch 6 and Patch 7 I am using High Power Mode (under Battery).
