Well then, the first thing for you to check is if "XWin -engine 1" has 
acceptable performance.  If not, try "XWin -fullscreen".  The first of 
these tests will use the GDI-based bit block transfer function, while 
the latter will use the DirectDraw bit block transfer function.  Please 
report on the performance of both tests.

The ATI 8500 series had some versions of the driver that had terrible 
DirectDraw performance.  This was fixed by a driver update, but it was 
very difficult to get the driver update to actually install properly. 
If you have DirectDraw driver problems then you will likely notice 
problems in other DirectDraw-based apps, such as those that play video 
like Window Media Player or Real Player.  Your GDI-based performance 
(-engine 1) should be unaffected by a problem with the DirectDraw driver.

For more information on how ATI botched their drivers, and for a little 
info on how changes to certain system DLLs can affect performance, see 
the following:
