Phoronix posted their 20-Way Radeon comparison with open-source graphics for Steam on Linux gaming
When it comes to Linux gamers wanting a discrete graphics card backed by open-source drivers, the only solution right now to truly recommend for those serious about performance and making use of the hardware is really AMD Radeon graphics. While Nouveau has been making much progress, until re-clocking and other issues are worked out the performance can be unbearably slow depending upon the particular graphics processor or run into other problems. (Of course, when talking about proprietary graphics drivers on Linux, the story is entirely different, or if considering integrated Intel HD Graphics.) For those pursuing a AMD Radeon GPU for their own Steam Box/Machine build and hope to use the open-source Gallium3D drivers, here's some Steam on Linux gaming benchmarks from almost two dozen different GPUs.20-Way Radeon Comparison With Open-Source Graphics For Steam On Linux Gaming
Using the latest Radeon graphics drivers (Mesa 10.3 with Linux 3.17), I ran some fresh Steam Linux gaming benchmarks. In particular, I tested a few of Valve's original hits powered by the Source Engine.
