Thanks for the answer. I will just post one more comment here, because I don't know if I should file a new bug. Because I made some research and it seems that the cause for the problem could also be the proprietary nvidia drivers. For example Jamestown on my main PC (nvidia Geforce 450 gts, I think) also has performance problems with Unity, for example the mouse cursor in te main menu is laggy (and the game itself, too). starting it on a seperate x-server (ctrl+alt+f1, log in and then startx /usr/bin/ck-launch-session /opt/jamestown/Jamestown -- :1) solves that problem (like with I think every other game that feels laggy). But on my laptop (some ATI) the game Jamestown runs fine (except the last level). And that's a bit surprising, as my Desktop PC overall has a lot more performance than my Laptop. So this might be an nvidia issue. I'll test some more games, if they run under unity on my laptop also better than on my desktop.
I think it would not really help a lot to report an nvidia-issue here, right? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987304 Title: [regression] [precise] 3D apps run much slower under Unity To manage notifications about this bug go to: https://bugs.launchpad.net/ubutter/+bug/987304/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
