Linux 3.4 Kernel Benchmarks
When running Lightsmark for the mobile Quadro GPU with the mainline Nouveau driver, for this first OpenGL benchmark, there is a noticeable performance improvement in moving from Linux 3.0 to Linux 3.1, but the Nouveau DRM in more recent kernels has not upped the frame-rates anymore for this test.
The OpenArena 0.8.5 results are flat-lined for Nouveau on this Lenovo ThinkPad laptop.
The more-demanding OpenArena 0.8.8 game has not been affected so much either by the recent Nouveau DRM changes in a stock configuration.
Like Lightsmark, Xonotic sees a nice performance improvement when upgrading from the Linux 3.0 to 3.1 kernel, but no extra frame-rates have been squeezed out of the kernel DRM driver since that point.
