I have a mid 2010 27" iMac with the maxed out graphics card, and while it is more than capable of handling this game at ultra high settings, it does so less than adequately at 2560x1440, which is the native resolution of my display.
When playing fullscreen, it appears that the Mac client immediately does a "fake full-screen" mode where it puts a frameless, full-sized window over your current resolution.
For me to play the game at 1920x1080, I need to
1: Go into System Preferences
2: Change my Display Resolution there to 1080p
3: Launch the game
And then when I am done playing, I need to do the same process in reverse.
Valve, Blizzard, EA and many other companies don't have a problem giving full screen resolution options inside their client... any chance we can get the same here?
It's not a game breaker, but it is horribly inconvenient.
