** Description changed: + [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.
