Jim, Every so often, the marine aquarium would kick out and leave the desktop showing on the monitor. Out of the desire to change something, I checked the "Wait for vertical sync" and it seemed to work. Can you tell me what checking that box dose?
Thanks,
Mike
Reduce the framerate of the Aquarium to match your monitor.
If you have a typical LCD monitor with a refresh of 60Hz, then the Aquarium really only needs to generate 60 frames per second, not hundreds.
