  • Proton 3.7 Updated, More RADV Fixes To Help Steam Play Gaming

    Overnight Valve promoted their Proton 3.7-7 build with better alt-tab handling and full-screen behavior for many games. There is also fixed mouse behavior and DXVK 0.80 is now used for the Direct3D-11-over-Vulkan translation to yield better Steam Play gaming performance.

    Steam Play 3.7-8 is also now available in beta with minor compatibility fixes, which Valve says is in preparation for future Proton versions.

  • AMD Stages A Number Of Fixes Ahead Of Linux 4.20~5.0 - Plus Vega 20 "MGPU Fan Boost"

    Following several interesting and exciting feature pull requests for the next Linux kernel (to be released as either version 4.20 or 5.0), AMD developers have moved onto stabilizing this massive amount of new feature code.

    The first "fixes" pull request was submitted today to DRM-Next focusing on stabilizing and fixing issues stemming from all this new code. As a reminder, that feature code ranges from AMD Picasso APU support along with Raven 2, a lot of Vega 20 enablement code including compute support, initial xGMI support, VCN dynamic power gating, DC display code enhancements, VCN JPEG engine support, Raven Ridge GFXOFF support, GPUVM virtual memory performance improvements, and a variety of other interesting work.

  • NVIDIA's Guide For Getting Started With RTX Ray-Tracing In Vulkan

    Last month's Vulkan 1.1.85 release brought NVIDIA's experimental ray-tracing extension (VK_NVX_raytracing) while for those curious how this fits into the Vulkan workflow, NVIDIA today published a guide for getting started with ray-time ray-tracing in the Vulkan space.

  • Freedesktop.org: its past and its future

    At the 2018 X.Org Developers Conference (XDC) in A Coruña, Spain, Daniel Stone gave an update on the status of freedesktop.org, which serves multiple projects as a hosting site for code, mailing lists, specifications, and more. As its name would imply, it started out with a focus on free desktops and cross-desktop interoperability, but it lost that focus—along with its focus in general—along the way. He recapped the journey of fd.o (as it is often known) and unveiled some idea of where it may be headed in the future.

    The talk was billed with Keith Packard as co-presenter, but Packard could not make it to XDC; Stone said that he sent Packard a copy of the slides and heard no complaints, so he left Packard on the slide deck [PDF]. Stone wanted to start with the history of fd.o, because there are lots of new contributors these days—"which is great"—who may not know about it.

Intel Core i9 9900K vs. AMD Ryzen 7 2700X Linux Gaming Benchmarks

Complementing the just-published Intel Core i9 9900K Linux benchmarks with the launch-day embargo lift are the Linux gaming benchmarks... This article is looking at the Linux performance between the Core i9 9900K and AMD's Ryzen 7 2700X in a variety of native Linux games as well as comparing the performance-per-Watt. So if you are a Linux gamer and deciding between these sub-$500 processors, this article is for you. If you didn't yet read the main article that features a 15-way CPU comparison on Ubuntu 18.10 with the Linux 4.19 kernel, here is a recap of this new Coffeelake refresh CPU. The Core i9 9900K is an eight-core / sixteen-thread processor with 3.6GHz base frequency and 5.0GHz turbo frequency. This 14nm CPU has a 16MB L3 cache, dual channel DDR4-2666 support, and a 95 Watt TDP. There is also the onboard UHD Graphics 630, but if you're a gamer, that isn't going to cut it. The Core i9 9900K is launching at $499 USD. Read more

Intel Core i9 9900K Linux Benchmarks - 15-Way Intel/AMD Comparison On Ubuntu 18.10

Intel sent over the Core i9 9900K as their first 9th Gen Coffeelake-S CPU hitting store shelves today. With the embargo on that now expired, let's have a look at how well this eight-core / sixteen-thread processor performs under Linux. The Core i9 9900K is Intel's new answer for competing with the likes of the AMD Ryzen 7 2700X, but does come at a higher price point of $499 USD. While the Core i9 9900K is a Coffeelake refresh, rather than being six cores / twelve threads, they are matching AMD's precedent set by the Ryzen 7 processors in having eight cores / sixteen threads. This 14nm 8C / 16T processor has a base clock frequency of 3.6GHz with a turbo frequency at 5.0GHz, a 16MB L3 cache and supports dual-channel DDR4-2666 memory. Read more
