November 26, 2012 -- In this article is a large OpenGL performance comparison looking at the frame-rates in different Linux games for different AMD Radeon Linux graphics cards when running the stock Ubuntu 12.10 operating system (Mesa 9.0 + Linux 3.5), the Catalyst Linux driver (fglrx 9.0.2) as found in the Ubuntu Quantal archive, and then when running the very latest Radeon Git code: The Linux 3.7 kernel, Mesa 9.1-devel, and xf86-video-ati 7.0.99 Git.

November 22, 2012 -- Last week marked the release of a new AMD Catalyst Linux driver beta that was intended to improve the AMD Radeon OpenGL performance. AMD said this updated closed-source Linux graphics driver would bring "significant performance improvements" for Valve's recently ported Left 4 Dead 2 Linux game. Curious about AMD Linux OpenGL performance improvements elsewhere, I ran some benchmarks of this new driver on several different graphics cards. Unfortunately, the performance improvements aren't too widespread and there's other problems making this beta driver not appealing.

November 08, 2012 -- This week NVIDIA began advertising their new "R310" Linux graphics driver that "delivers [a] massive performance boost to Linux gaming" as a result of Valve releasing their Steam Linux Beta. The NVIDIA 310.xx Linux graphics driver not only improves the performance for Valve's Source Engine games, but many Linux OpenGL games. In this article are benchmarks from three graphics cards to highlight the optimizations.

November 06, 2012 -- Similar to last week's testing of comparing the open-source vs. closed-source Radeon Linux driver performance from a stock Ubuntu 12.10 installation, the tables have now been turned to look at NVIDIA hardware on this latest Ubuntu Linux release. Benchmarks were done of the stock Nouveau open-source graphics driver, the official NVIDIA proprietary driver, and the proprietary driver when it was underclocked to match the clock frequencies as used by the reverse-engineered Nouveau driver.

November 03, 2012 -- With 2D color tiling enabled by default in the R600 Gallium3D Radeon open-source driver as of this week, here are new benchmarks showing off the OpenGL performance impact of the 1D and 2D tiling methods for this common open-source AMD Linux graphics driver.

November 02, 2012 -- Following performance benchmark results I published earlier this week comparing the open-source Radeon and AMD Catalyst driver performance under Ubuntu 12.10, Marek, the well-known independent open-source graphics driver developer, set out to explore some of the performance issues in the open-source driver. One day later, he published a patch that could quadruple the frame-rate of the Radeon Gallium3D driver. He went on to push another performance-focused patch too for this R600g driver. In this article are a fresh round of benchmarks of the open-source driver to look at the wins and losses attributed to this new code.

October 30, 2012 -- With Ubuntu trying to improve their OpenGL driver support state to push the Linux OS as a platform for gaming, Valve going to be promoting the closed-source NVIDIA and AMD drivers on Linux, and various other challenges still turning up for those trying to use the different Linux OpenGL drivers, here are some new benchmarks comparing the open-source Radeon Gallium3D driver against the closed-source AMD Catalyst driver.

October 18, 2012 -- With the NVIDIA 310.14 Beta driver introduced at the beginning of this week there are some OpenGL performance improvements in general plus an experimental threaded OpenGL implementation that can be easily enabled. In this article are benchmarks from the NVIDIA GeForce GTX 680 with this new Linux driver release.

October 11, 2012 -- LLVMpipe is gaining traction on the Linux desktop as means of being the default software-accelerated OpenGL fallback. The open-source LLVMpipe driver is even being used for the Unity desktop and GNOME Shell fallback by some distributions when no GPU driver is available (although KDE doesn't plan to take the LLVMpipe route). In this article are benchmarks showing the Gallium3D LLVMpipe performance if attempting to run OpenGL games on this driver running atop a modern CPU.

October 08, 2012 -- After some dabbling this weekend with Ubuntu 12.10 on both the Nouveau and NVIDIA graphics drivers, there's both good and bad news to share.
