wow, this is the first time I've had any test beat the opengl version...(fullscreen anyway), I had to run these test about 4 times each just to make sure. it is kind of weird though because the test's fps doesn't seem to be very consistent for me between multiple runs using any of the drivers. I think this test chokes the advantage that opengl normally has in fps.
