On Low-End GPUs, Nouveau Speeds Past The NVIDIA Driver
Phoronix: On Low-End GPUs, Nouveau Speeds Past The NVIDIA Driver
While the Linux 2.6.38 kernel has been out for less than one week, if you use NVIDIA graphics, particularly with a low-end GPU, start counting down the days to the release of the Linux 2.6.39 kernel. Particularly on lower-end NVIDIA GeForce graphics cards, the reverse-engineered open-source Nouveau driver now meets or exceeds the speed of NVIDIA's official proprietary driver in a number of OpenGL test cases...

Is there any change you could postfix any prerelease kernels with -pre or -rc as it get's confusing when you're talking about testing 2.6.39 when rc1 hasn't even been tagged yet
Look at the number of articles you have testing 2.6.38 which has only been out for a short time
It's great that even Nvidia users have a choice!
Could it be that you are using a high-end CPU in the testing system?
Testing a Geforce 8500 on a six-core i7 with a gpu driver that is mostly CPU bound seems pointless to me ...
That's exactly what wouldn't happen. A low-end GPU on top of a high-end CPU would mostly likely - not - stop at the driver's CPU bottlenecks.

yes you are, that "the reverse-engineered open-source Nouveau driver now meets or exceeds the speed of NVIDIA's official proprietary driver in a number of OpenGL test cases..." means it was not as fast as the nvidia binary scoring before, not that it now beats it at a few .% now...

The nouveau driver would definitely be ideal for those cards that aren't supported by the blob any longer, such as the GeForce 5 and older. The GeForce 6 and 7 series can also benefit too. At some point it'll be possible to support the newest cards once the devs figure out how to turn on the antialiasing modes and to make use of the stream processors. I have to admit that the Nouveau driver has made great strides despite not having any support or documentation from nVidia.
