Hi, I have the rMBP 2.6 ghz i7 with 16 gb of ram. I have my computer off of the battery saving preferences when I play games, so it is instantly using 650M. I've been playing and the game is a steady 30 FPS but I thought it'd be higher. What is the issue here? My default settings are put on high and I have V-Sync on because the screen tearing was terrible. Other than that, shouldn't my computer be killing this thing at atleast 50 FPS? Help, thanks.
