I finally found some time to test some other drivers. With NVIDIA 295.49 drivers the same "drop in performance" issues appear.
When running Nouveau, the issues are gone. Glxgears reports around 650 FPS with Nouveau. With nouveau the desktop looks streched, but I have not looked into that further yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1032187 Title: Major OpenGL performance degradation over time To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/1032187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
