Nouveau For Open-Source NVIDIA In Mesa 8.0 Is Mixed
When running the Warsow game at 1920 x 1080, the Fermi Nouveau performance is obviously still very slow by default, the 9800GT is over three times faster on the binary blob, there's still a measurable difference with the GeForce 9500GT, and the GeForce 8600GTS results remain surprisingly good, but not improved by going from Mesa 7.11 to Mesa 8.0.
Lightsmark is unstable with the Nouveau driver in a few different configurations, but except for the 8600GTS, the open-source Mesa performance is well behind NVIDIA's reliable closed-source offering.
