NVIDIA GeForce 600 "Kepler" On Open-Source: It's Uselessly Slow

[LEW21]

Wow, finally, open drivers are fast enough to run all these games with playable FPS in HD! That's a reason to celebrate!

Yes, I too think the title is too sensationalist. It is only slow in comparison to what it is potentially able to do and probably in comparison with performance / watt. Practically these FPS numbers are far from "uselessly slow".

Aside from Doom 3 and Nexuiz, I think it's worth celebrating that nouveau got more than 50 frames per second in all of the tests.

Well, what did you expect ... at these high resolutions, the low clock speed is QUITE limiting, you won't notice any improvements with that. Not that there were any ... Xonotic seems playable, and even competitive with blob at low settings, so wouldn't call it completely useless.
And it's not like it's much slower than r600g or radeonsi either, and those are usually at max clocks, you don't call that useless. Granted, GTX680 is quite powerful.

Phoronix: NVIDIA GeForce 600 "Kepler" On Open-Source: It's Uselessly Slow

With the Linux 3.8 kernel that's presently under development, the open-source reverse-engineered Nouveau driver for supporting NVIDIA graphics processors has seen some significant changes. One of the late changes was enabling Kepler acceleration support. While there is now an "out of the box" open-source GPU driver that supports the GeForce 600 GPUs with 3D/OpenGL acceleration, it's incredibly slow.
