Lee,
I'm running in 16bit with the 5382b08 driver from ATI's site.
When I moved to this driver, my performance increased noticably. This was the most
stable
and fastest driver from ATI that I've found for my video card. It's claimed to be a
'beta' driver,
but if that doesn't bother you or you just want to try it, it can be found at:
http://www.ati.com/na/pages/spdrivers/index.html
at the end of the list.
