Upgraded Kernel & Mesa Yield A Big Boost For Athlon R3 Graphics

Filed under
Graphics/Benchmarks
Ubuntu

With OpenArena the frame-rate went from just 8 FPS on Ubuntu 14.04 LTS to 19 FPS when using the Linux 3.14 kernel. Linux 3.14 allows for the R3 Graphics to re-clock to their highest performance state compared to Linux 3.13 where DPM isn't enabled by default for GCN GPUs. When going to Mesa 10.2-devel that will be officially released in about one month, the frame-rate rose to 25 FPS... That's over a three-fold performance improvement when pulling in the bleeding edge latest code.

Linux

This past weekend I wrote about NVIDIA planning to release a huge Linux driver update that would finally bring overclocking support under Linux to GeForce 400/500/600/700 series hardware. That milestone has now been realized with the 337.12 Beta driver release and besides overclocking it has a bunch of other features.

Open-Source Graphics Performance With Unvanquished

Filed under
Graphics/Benchmarks
OSS

To celebrate these improvements being made, I ran a variety of open-source driver tests with this game's test profile. The tests were limited to AMD Radeon and Intel HD Graphics hardware as the NVIDIA GeForce GPUs would end up generating DRM errors when running Unvanquished with its advanced visual settings. The GPUs tested out-of-the-box on Ubuntu 14.04 LTS with this latest Unvanquished version include.

Graphics/Benchmarks
Ubuntu

Last week we covered a 13-way Radeon GPU comparison on Ubuntu 14.04 and we also looked at the state of Nouveau on Ubuntu 14.04 with many NVIDIA GeForce graphics cards. In concluding our latest round of open-source graphics driver tests from the upcoming Ubuntu 14.04 LTS "Trusty Tahr", here's a 20-way graphics processor comparison using AMD Radeon, NVIDIA GeForce, and Intel HD Graphics hardware.

Nouveau Picks Up Slightly Better OpenGL 4.0 Support

Filed under
Graphics/Benchmarks
OSS

The newly exposed extensions by the Nouveau Gallium3D code include ARB_texture_gather and ARB_texture_query_lod. The Intel Mesa driver had already supported both of these OpenGL extensions while the R600/RadeonSI Gallium3D drivers supported the latter extension as well.

Nouveau Becomes Friendly Towards Non-Root X Server

Filed under
Graphics/Benchmarks

The xf86-video-nouveau driver as of today supports server-managed file descriptors. As explained in the earlier Phoronix article, Last month we wrote about Red Hat working on a suid root wrapper for the X.org Server and other improvements being led by Red Hat's Hans de Goede to run Xorg in more configurations without needing root support. As part of this, sever managed file descriptors (FDs) has been one of the changes needed by the X.Org graphics drivers for supporting this change of running the xorg-server without root rights. Besides needing changes to the DDX drivers and the X.Org Server (those changes are landing with X.Org Server 1.16 this summer), systemd-logind is also needed.

13-Way Radeon Graphics On Ubuntu 14.04 LTS

Filed under
Graphics/Benchmarks
Ubuntu

Stay tuned for the NVIDIA and Intel results that will accompany the AMD Radeon performance numbers in the days ahead. Overall, the Ubuntu 14.04 LTS open graphics experience is decent with Linux 3.13 and Mesa 10.2-devel although Linux gamers and enthusiasts are encouraged to either use the proprietary drivers or at least upgrade to the latest Linux kernel (3.14+) and Mesa 10.2-devel for the best OpenGL performance and best feature-set.
