Thanks, this is one of the better crafted performance bug reports I've seen so far.
One thing you could try is the 2.6.28-11.40 kernel. That kernel (and only that kernel) includes the MCHBAR patch which has been seen to improve performance for some people. It unfortunately was proven to cause a serious freeze issue on some hardware so had to be reverted in the #41 kernel, but if it solves this performance problem that would be an extremely useful piece of data. -- [G33] performance drop (20-40fps) in games and compiz after upgrade to Jaunty https://bugs.launchpad.net/bugs/359629 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 -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
