Dear Denis and List,

ATI released a new set of drivers today so I ran tests on
a Radeon 7000 and 8500. I ran cluttest with fixRadeon
in and without. Without the fix the 8500 reports no errors
but the 7000 is off by 1 at times. With the fix in the 7000
reports no errors but the 8500 is off by 1 at times. I also
ran screentest and CopyWindows speed is up to 33Mbyte
for the 7000. There seems to be some interaction with
PCI ATI cards and MATLAB that really slows down the
CopyBits speed. I ran TimeVideo without MATLAB running
and the CopyBits speed goes up significantly on the 7000.
I've attached all test results below. Here is a newsgroup link
for the ATI drivers. Take care,

Doug
