Can you confirm the CPU usage drops significantly when vsync is disabled? To disable vsync... 1. Run "ccsm" (from the "compizconfig-settings-manager" package) 2. Go to the OpenGL section and untick "Sync To VBlank".
Also, can you please confirm whether the problem only occurs with the latest nvidia driver? Did it happen with 295.40? Does it happen with nouveau? ** Changed in: unity (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997170 Title: Unity 3D is slow with driver 295.49 and GeForce 7000M / nForce 610M.
