That said, I ran some tests at native res on a 27" 2011 6770m (2560x1440) with 12GB of RAM. I did shut down any misc programs running, but I didn't go so far as to shut down any 'extra' stuff I have that always runs, like bonjour or plex media manager.

With extreme and ultra settings on a replay at 2x speed, which gave an FPS of 18-21. It didn't seem to make a lot of different how much was going on on the screen, and there was no discerenable difference between ultra and extreme.

At High settings native res, it was slightly faster. I was running between 19 and 22 fps.

At Medium suddenly the FPS stayed at 29 most of the time, with a range of 27-31. This was perfectly smooth gameplay imo.

None of these are really 'unplayable' for an RTS type game, but I think the medium / native 2580x1440 res or dropping down to 1920x1080 at the ultra settings yields the best gameplay on this particular iMac. To be honest, I cannot see much difference between 1920x1080 and 2580x1440 within the game. The difference is startling on the OS X desktop though.
If you do a ctrl alt f while in game it brings up an fps counter in the top left corner, that's how I did it. I played through the last quarter of SC2 with that on and it basically played at maxed out settings at 30-50 fps easily. Don't know if that actually makes a dif.
