Re: [pygame] vista testing...

Cool.  Seems like we're getting closer to figuring this thing out...


Two more tests to try:

1. Try with the dummy video driver to see if there are still scratchy noises.
import os
os.environ['SDL_VIDEODRIVER'] = 'dummy'

This will tell us if a video driver is having an effect.

2. try pygame program with a 4096 sized buffer.

This will let us know that a 4096 sized buffer magically works better :)


cu,
