Anyone out there try running the "Game of the Year" edition of Batman: Arkham City on a machine with the OS X Mavericks GM yet? I tried it on a 2008 Mac Pro tower using a Radeon 6870 graphics card, and it was odd. The first time I ran it, I got it to run full screen on one of my 2 displays in the 1600x1024 resolution mode - but after 10 minutes or gameplay or so? The screen suddenly went black. I could still hear the background sounds and tell the game was running, but no more video. I had to force-quit out of it to exit. Ever since then, I haven't been able to get it to run full-screen at all. It just plays the intro screens as it starts up and then goes to a black screen instead of the main menu. If I tell it to run in a Window specifically, then it seems to work just fine -- but only in a small window. (No matter what screen resolution I select, it doesn't seem to make the window it uses larger or smaller? I'd say it looks like maybe it's using something like 800x600 resolution, judging by the window size.) I checked to see if any update patches existed, but so far apparently not for this one. I'm on version 1.0 and that's all they have for it from Feral.
