I suspect the problem is a compiz/nvidia issue with two screens. I normally have the following setup:
* laptop monitor - 1680x1050 - screen 1 * external monitor - 1680x1050 - screen 2 * wine is set to emulate a virtual desktop and CoD4 is set to run at 1680x1050. I usually run it on screen 2. After reboot, there are no issues with frame rates. After some hours, the framerate performance degrades significantly (to half or worse) unless: * I disable compiz. * OR I run wine without emulating a virtual desktop, in which case I get 'full screen mode' on the laptop screen * OR I set the screens to be clones. So after reboot compiz recognises that the wine window is not supposed to have desktop effects applied (whether it runs on screen 1 or 2), but after some hours it must be trying to do something with the screen drawing operations and slowing down frame rates. -- compiz performance degrades over time https://bugs.launchpad.net/bugs/380129 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
