Unrelated to this driver, but i also found that 32bit fglrx is also slow on the same thing... GTT_WC while running some 32bit apps simply made things much slower. Of course no idea how to do anything with that driver to 100% approve that :)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
