Thanks, Oliver. I tried this and the performance was the same running burnP6 and running it with a nice level of -1. Strangely, with up_threshold set to 40, there was never a drop in performance: as soon as I changed it back to 95, the drop in fps was immediate. Running glxgears actually increased fps in CoD4!
Then I discovered that once performance gets reduced to this level, turning off compiz restores it (normally it makes no difference). Turning compiz back on had some strange effects - after I closed CoD4, video performance dropped dramatically - I could see the screen redrawing pixel line by pixel line. Changing to a console (ctrl-alt-f1) and back fixed it. So it must be a compiz problem, not a scheduling problem. -- CPU Scaling too aggressive https://bugs.launchpad.net/bugs/107545 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
