I came from a MacBook with the 9400m where Diablo worked fine in fullscreen. I currently am trying to run it in my Mac Pro on a 7300 GT, running 10.6.7 (waiting for sis to send updates via flash drive, can't download ***** here). Software rendering works in fullscreen but it's not pretty. OpenGL in fullscreen results in stretched widescreen and full of black blocks messing up the screen making it totally unplayable. CMD+M gets me a windowed mode where everything looks fine but at 1920x1080, it's pretty darn small. Any ideas? Is it my stupid video card?
