City of Heroes runs, but not well I was able to get City of Heroes to run on a new MBP by following supagold's hints: http://forum.parallels.com/showthread.php?p=64183&highlight=city+heroes#post64183 (I didn't use the tweaker, I was able to switch to Windowed mode within the game.) But no amount of graphics tweaking could get it faster than about 5 to 10 frames per second. Granted, I was in PocketD at the time so it might have done better in a calmer location. But it really was not playable. Note that CoH requires DirectX 9, which Parallels does not support ("Limited 8.1"). I did notice that the drivers installed by Parallels claim to support DirectX 9 (dxdiag), which is probably why the game attempted to run despite the lack of true support. I ended up installing Boot Camp on the destination machine instead. FWIW, a new MacBook Pro does generate a LOT of heat running CoH in BootCamp, but the fans did come on full blast. I saw some posts in the CoH forum about someone's (older?) MBP overheating due to the fans not comming on, but that doesn't appear to be a problem with the new MBP and BootCamp 1.3. Of course, whenever CoH does run under Parallels, it'll be back to that for all the usual safety, reliability, and convenience reasons.
