XWayland Gets Patches For Better EGLStreams Handling

While the recently released X.Org Server 1.20 has initial support for XWayland with EGLStreams so X11 applications/games on Wayland can still benefit from hardware acceleration, in its current state it doesn't integrate too well with Wayland desktop compositors wishing to support it. That's changing with a new patch series.

Wine's VKD3D 1.0 Released For Running Direct3D 12 Over Vulkan

The Wine project has announced the release of VKD3D 1.0, the first official release of this Direct3D 12 over Vulkan layer primarily developed at CodeWeavers. VKD3D is the approach Wine is pursuing for getting Direct3D 12 games from Windows working on Wine under Linux or also under macOS when paired with MoltenVK.

GCC vs. LLVM Clang vs. AOCC Compilers On AMD Threadripper

Given recent improvements to AMD Zen (znver1) with LLVM, the new AMD AOCC 1.2 compiler release, and GCC 8.1 having premiered just weeks ago, here is a fresh look at the performance of six different C/C++ code compilers when testing the performance of the resulting binaries on an AMD Threadripper 1950X system.

Qt 5.11 Released With A Big Arsenal Of Updates

The Qt Company has managed to release Qt 5.11 one week ahead of schedule compared to its original road-map, which is quite a feat considering some of the past Qt5 release delays. Beyond that, Qt 5.11.0 is offering a big slab of improvements.

DragonFlyBSD 5.3 Works Towards Performance Improvements

Given that DragonFlyBSD recently landed some SMP performance improvements and other performance optimizations in its kernel for 5.3-DEVELOPMENT but as well finished tidying up its Spectre mitigation, this weekend I spent some time running some benchmarks on DragonFlyBSD 5.2 and 5.3-DEVELOPMENT to see how the performance has shifted for an Intel Xeon system.

Looking Ahead To The Linux 4.18 Kernel

There still are several weeks to go until the Linux 4.17 kernel will be officially released and for that to initiate the Linux 4.18 merge window, but we already know some of the features coming to this next kernel cycle as well as an idea for some other work that may potentially land.

Ryzen 7 2700 / Ryzen 7 2700X / Core i7 8700K Linux Gaming Performance With RX Vega 64, GTX 1080 Ti

With the Linux benchmarks of the Ryzen 7 2700 last week I included a few Linux gaming benchmarks, but for those evaluating CPU options for your next Intel/AMD Linux gaming system upgrade, here is a much more thorough set of benchmarks from a wide variety of OpenGL and Vulkan powered Linux games. The Ryzen 7 2700, Ryzen 7 2700X, and Core i7 8700K processors were tested for this Ubuntu gaming comparison while testing with both a Radeon RX Vega 64 and GeForce GTX 1080 Ti.

AMD AOCC 1.2 Code Compiler Offers Some Performance Benefits For EPYC

Last month AMD released the AOCC 1.2 compiler for Zen systems. This updated version of their branched LLVM/Clang compiler with extra patches/optimizations for Zen CPUs was re-based to the LLVM/Clang 6.0 code-base while also adding in experimental FLANG support for Fortran compilation and various other unlisted changes to their "znver1" patch-set. Here's a look at how the performance compares with AOCC 1.2 to LLVM Clang 6.0 and GCC 7/8 C/C++ compilers.
