A different operating system would be using different drivers and different sections of memory, so it's still concievable that there's a hardware problem (though less likely).

As far as resolution, MA simply checks the card's list of available resolutions, and picks the highest one. Whether the card runs out of VRAM depends on a lot of things. Of course, the most important is the amount that the card starts out with. But every open window, fish, background object, etc., uses up some of it. An 800x600 screen uses 1,920,000 bytes for each buffer (2 flip buffers, and an off-screen refresh buffer). That's 5,760,000 bytes even before we add fish and background. A 1280x960 screen uses 14,745,600 bytes for the three buffers, more than twice as much as 800x600.

Give the lower resolution a try, it just takes a second and would provide important info.
