Well, this is strange. I did think it was odd that the
targetBackground.py demo would be too much for my card to handle. I do
have the video card set at the right frequency - 75Hz - and when I run
programs windowed I get the time values clustered at 13ms, as you
would expect. However, for some reason when I run any of the demos
full screen, I get what appears to be a 60Hz refresh rate...
To be absolutely clear, I have resolution set to 1024x768, 75Hz, and
when I run any of the demos at this resolution, but leave the
Fullscreen box unchecked, I get 75fps. Checking the box invariably
gives me 60Hz. I never noticed this before. Any ideas?
