I have exactly the same performance problems with a gtx680 running ubuntu 12.04.
Running Trine 2 with vsync on gives me 40 fps and 100 without vsync (enabled on nvidia cp). But even at 100 fps gameplay is stuttery. Also, a curious observation, when unredirect full screen window is enabled I get 40 fps, but when it's disabled I get constant 60 (stuttery), but I can see ubuntu panels. A free game that you could test, and see how awful compiz is running, is Alien Arena Reloaded. It doesn't matter how much you tweak in ccsm, you'll get terrible stuttering. And just to add, till now, nothing has changed between ubuntu 12.04 and 12.10 alpha3. Infact, it's even worse performance, because even moving a window experience stuttering. Running in gnome classic (no effects), no stutter, no tearing, no performance issues, all is fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1029085 Title: Stuttering in games with high fps and Nvidia To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1029085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
