Open-Source Nouveau Driver Remains Slow For NVIDIA's Fermi, Kepler

When running the id Tech 4 Prey game, only the GeForce GTX 680 graphics card was close to running at 60 FPS on Nouveau.

Even for the ioquake3-powered Reaction game, the only graphics card capable of delivering consistently playable frame-rates was the GeForce GTX 680.

The Unigine engine results are obviously very disappointing with the graphics card's core, shader, and memory clocks stuck to very low frequencies with Nouveau.
