Don't Bother Trying AMDVLK Vulkan With Rise of the Tomb Raider Right Now

Following yesterday’s 20-way graphics card comparison for Rise of the Tomb Raider that debuted yesterday on Linux and is exclusively powered by Vulkan, my next benchmarking objective was trying out the official AMD Vulkan driver, AMDVLK, to see how it would work given the successes of RADV on launch-day for this latest Feral Interactive game port…

20-Way NVIDIA GeForce / AMD Radeon GPU Comparison For Rise of The Tomb Raider On Vulkan/Linux

Today Feral Interactive released their much anticipated Linux port of Rise of the Tomb Raider, the game that was released for Windows in January of 2016 and then released for macOS last week. Feral’s Mac port was relying upon the Apple Metal API while the Linux port is now their second game (after F1 2017) exclusively relying upon the Vulkan graphics/compute API rather than OpenGL. This morning I posted the initial Radeon results using the RADV driver while here is the NVIDIA GeForce vs. AMD Radeon graphics card comparison on Ubuntu Linux using twenty different graphics cards.

Linux Gaming Performance With AMD Ryzen 5 2600X / Ryzen 7 2700X

Today the Ryzen+ “Pinnacle Ridge” processors begin shipping and we can now share with you the initial performance results for the Ryzen 5 2600X and Ryzen 7 2700X processors. One of the most common questions I’ve received about these improved Zen processors since showing them off last week was inquiries/hopes about the Linux gaming performance, so those numbers are first up today followed by other Linux benchmark results forthcoming.

Rise of the Tomb Raider Linux Performance On AMD Radeon GPUs

Yesterday Feral announced that the long-awaited Linux release of Rise of the Tomb Raider would be coming tomorrow and now they have honored that release. Rise of the Tomb Raider is now natively available for Linux and this port is exclusively relying upon the Vulkan graphics API for rendering. Here are our initial benchmarks of Rise of the Tomb Raider on Linux with Radeon GPUs while making use of the Mesa RADV driver.

RadeonSI Now Appears To Support "RX Vega M" With Intel Core CPUs

One of the most common Linux hardware questions I’ve received dozens of times in the past few weeks alone has been over the support for “RX Vega M” Vega-based graphics processors found on select newer Intel Kabylake CPUs. It appears RadeonSI at least should now support these Radeon graphics on Intel CPUs…

Meltdown/PTI Mitigation Impact On BSDs vs. Linux

Besides the fresh BSD/Linux disk performance tests, some other tests I ran on various BSDs and Linux distributions this week was looking at the performance impact of Intel Meltdown CPU vulnerability mitigation on each of them, namely the performance impact of using kernel page-table isolation…
