Can everyone who has a slowdown when fullscreen please try the two tests in this download?

You'll need to run it for a few seconds, then push Esc to quit. In the Terminal window that opened when you double-clicked the app, you should now see something like:
SPINNING CUBE FRAME RATE (WINDOWED):
1259.84 frames per second
Let me know what frame rates you're seeing for each. Do note that windowed well be several times faster than fullscreen. I get:
Fullscreen: 375 frames per second
Windowed: 1259 frames per second
This is to be expected, given that the windowed version draws much less data. But if you get something like 18 fps for fullscreen, something's up...
