To verify if CPU scheduling is your problem you could try "cpuburn". Commands in this package are: burnP6, burnK7, ect. (optimized for different CPU types) and they just waste CPU cycles. Run your test-app with higher prio together with burnXY:
$ burnP6 & $ sudo nice -1 wine CoD4 If your test app shows much more or less(!) jitter than when running alone, then there is a problem with CPU scheduling and/or power-saving on your system. If it does not make a big difference, then it is more likely a problem with the video driver, DMA transfers or similar. About me: I am not a Linux kernel guru. Me too, I just saw these CPU scaling issues since Hardy. Here they were gone since Jaunty final. But I am glad to help finding the cause or solutions for systems which are still affected. -- 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
