Just some observations: Updating mesa fixes the issue with my current ingame configuration (which is vsync off). I tracked this down to [url=<a href="http://cgit.freedesktop.org/mesa/mesa/commit/?id=f7a355556ef5fe23056299a77414f9ad8b5e5a1d]glx/dri3">http://cgit.freedesktop.org/mesa/mesa/commit/?id=f7a355556ef5fe23056299a77414f9ad8b5e5a1d]glx/dri3</a>: Use four buffers until X driver supports async flips[/url]. I had vsync disabled since initially I wanted to benchmark the HSW. With PRIME and vsync disabled ingame the rendering however is very 'shacky', to the point where it's not playable. I thus re-enabled vsync and the issue reappeared (strange I guess). Initial tests show that [url=<a href="https://www.freedesktop.org/patch/34966/]Correct">https://www.freedesktop.org/patch/34966/]Correct</a> present_notify_msc vblank target[/url] seems to fix the issue (with vsync on).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
