Hmmm... Works awesome in lower resolutions, but at 1600x1200, which is what I need. When I click "test",I get wierd OpenGL stuff, most cubes are drawn in pieces that are solid blue rather than opaque and I mostly see lots of solid lines running through the cubes. When I try the actual saver, I now get 1 frame every 2 seconds of blue lines instead of 1 frame every 5 seconds. Looks like the double buffering helped! =) I'm sure lower resolutions are fine, but not for me. I wish these other openGL savers would let their secret out for smooth animation at 1600x1200. This is frequently a problem.
