A Soft Implementation Of ARB_gpu_shader_fp64 Is Slowly Being Tackled For Mesa

Last year there was a Google Summer of Code student working on a library to implement double-precision operations (FP64) in pure GLSL 1.30 as a benefit to older GPUs not having native FP64 capabilities. While that work didn't materialize as a solution in 2017 for those wanting "soft" ARB_gpu_shader_fp64 for being able to potentially expose OpenGL 4.0 on more R600g era GPUs, the work is ongoing.

UKSM Is Still Around For Data Deduplication Of The Linux Kernel

Several years back we wrote about Ultra Kernel Samepage Merging (UKSM) for data de-duplication within the Linux kernel for transparently scanning all application memory and de-duping it where possible. While the original developer is no longer active, a new developer has been maintaining the work and continues to support it on the latest Linux kernel releases.

Wayland's Weston 2.0 Compositor Released

Wayland 1.13 was released earlier this week but the adjoining Weston compositor update didn't happen at the same time due to some last minute changes needing more time to test, but this Friday, Weston 2.0 is now shipping.

Fresh RadeonSI Mesa Git Gaming Benchmarks On 7 Linux Desktops

When posting last week our Windows 10 vs. Ubuntu Radeon benchmarks and Windows vs. Linux NVIDIA Pascal benchmarks and then the Windows vs. Linux relative performance analysis, as usual, it didn't take long for some to argue that the Linux gaming performance is actually faster but "Unity 7 is slower" and the similar FUD that is usually waged whenever looking at cross-platform performance.

Fuzzing Mesa Drivers Begin To Uncover Bugs

Last December we wrote about work being done on fuzzing OpenGL shaders leading to wild differences with the work being done at the Imperial College London. While they were testing other drivers on different operating systems, they have now fired up tests of Mesa.

Trying Nouveau With HITMAN On Linux Doesn't Get Too Far

Chances are if you are using a NVIDIA GeForce graphics card and planning to game on Linux you are using NVIDIA's official Linux driver, but in case you are trying to use the free software Nouveau driver stack, I tried running Feral's recent HITMAN game release with this open-source NVIDIA driver.

GLSL/TGSI On-Disk Shader Cache Lands In Mesa For R600g/RadeonSI

Timothy Arceri who has been working on the Mesa on-disk shader cache for months and most recently began working for Valve on the AMD Linux driver stack has landed support in Mesa 17.1-devel for the GLSL/TGSI on-disk shader cache for the R600g and RadeonSI Gallium3D drivers.

Radeon vs. NVIDIA Performance For HITMAN On Linux With 17 GPUs

Last week Feral Interactive released the much anticipated Linux port of HITMAN, which debuted for Windows last year. Now that there's benchmark support for HITMAN on Linux, I have been running a number of tests for this game that's powered by the Glacier Engine and making use of OpenGL for rendering on Linux. In this article are our initial AMD Radeon performance figures making use of the RadeonSI Gallium3D driver compared to NVIDIA's driver and the assortment of GeForce results published yesterday.

The Vulkan Differences Between AMDGPU-PRO, RADV & SteamVR's RADV Drivers

With Valve having published a binary-only RADV Radeon Vulkan driver build for their beta of SteamVR on Linux, I did some poking out of curiosity to see the differences to the mainline RADV driver in Mesa. Out of curiosity I also did a comparison to see how the Vulkan capabilities compare to the proprietary AMDGPU-PRO Vulkan driver.

X.Org Weighed Moving Their Annual XDC Conference Out Of The US

XDC 2017, the annual X.Org Developers' Conference, was announced last year for happening in Mountain View, California and hosted by Google but given the current US political climate, the X.Org Foundation was questioning whether to move the event outside of the United States.

HITMAN Linux Benchmarks On 12 NVIDIA GPUs

Last week Feral Interactive released the much anticipated port of HITMAN for Linux. While at first it didn't look like this Linux game port would work out for our benchmarking requirements, thanks to Feral it does indeed work for another interesting Linux gaming test perspective. For our initial HITMAN Linux benchmarks are tests from 12 NVIDIA GeForce GPUs while our Radeon tests will come tomorrow.
