Reboot, note in bios what you're using
run BD in whatever settings you use.
Then hit the bios and reset the AGP aperture size to 32 and run BD again, jot down.
If you have time, do 256, 128 and 64 and 32, otherwise, just the extremes.
I've been all over ATI's site, all over Microsoft site and get differening info on the same website.
So, I ran some tests.
ok..common says use half of your card. MS says using slower system mem robs from card, use higher settings...
almost seems like the slower number give me higher score.
I'll try 4 later on
