Title: Much slower OpenGL frame rates with unityshell loaded, than plain compiz Status in Ubutter: Making Ubuntu buttery smooth: Fix Released Status in Unity: Fix Released Status in Unity 5.0 series: Fix Released Status in “unity” package in Ubuntu: Fix Released Status in “unity” source package in Precise: Fix Released Bug description: [Test Case] Performance issue - just checking if performance in OpenGL applications with Unity loaded are normal. [Regression Potential] Visual regressions, shell drawing problems. Part of a big change, many regression potentials. Original description: The main problem is that OpenGL apps run slower with unityshell compared to plain compiz (Gnome Classic). In extreme cases, running glmark2 under Unity only achieves 0-3 FPS. Yet on the same machine reports frame rates of several hundred FPS in Gnome Classic. See comments #28-#30. In other cases, game performance is OK but still visibly worse under Unity. ioquake3 drops in frame rate by around 20% in Unity compared to plain Compiz in Gnome Classic (see duplicate bug 1005074). ORIGINAL DESCRIPTION: On my Z600, with a fresh Precise installation, after installing the NVIDIA driver 295.40 (same version as in gPrecise), glxgears runs extremely slowly full-screen. When running on Precise, Chrome's GPU accelerated rendering path produces correct results, albeit extremely slowly.
