Are you sure openarena is refresh-rate limited? Last > time I tried, the openarena benchmark itself was disabling vsync.

(It is not normally if openarena changes the resolution itself via > SetVidMode.) The ultimate question is whether you are getting pageflips at > all. Also difficult to guess without the avg/max fps @ resolution.</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>
