An update: we tried upgrading the graphics card in the affected workstation from a Quadro FX 380 to a Quadro 600. This worked around the performance problems. With the new card, glmark2 runs smoothly within Unity, and Chrome runs well; it claims 60 FPS with the WebGL Aquarium demo running nearly full-screen, though it does appear to drop frames occasionally.
The Quadro FX 380 is admittedly a fairly old card, and I don't think it's worth investing a lot of time making things work flawlessly on it. However, I do believe the performance issues are indicative of problems with Unity+Compiz on older or slower graphics cards in general, and they should continue to be investigated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/988079 Title: Much slower OpenGL frame rates with unityshell loaded, than plain compiz To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/988079/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
