Confirms my subjective experience - the glamor based open-source driver stack is really slow for some operations. It seems the proprietary nvidia driver has way lower driver overhead (considering the 10x10 putimage won't saturate the GPU).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
