After the many years now that AMD's RadeonSI Gallium3D driver has been seeing relentless optimizations for GCN and now RDNA GPUs paired with the fact more Linux games targeting Vulkan (or going through Direct3D to Vulkan), one might think in 2022 that the OpenGL driver optimization efforts would let up... But that doesn't appear to be the case with well known AMD RadeonSI developer Marek Olšák pursuing yet more optimizations...

2022 will hopefully be the year that PipeWire becomes commonplace on desktop Linux distributions for managing both audio/video streams.

Next month marks two years since AMD introduced the Ryzen Threadripper 3990X 64-core / 128-thread processor. All of our testing of the 3990X on Linux over the past two years has been with the System76 Thelio Major, which continues holding up well with that US-assembled workstation with hand-crafted enclosure from Colorado. With System76 having recently released Pop!_OS 21.10 as the latest update to their Ubuntu Linux derived operating system and upcoming two year anniversary of the 3990X, it made for an interesting time to see how the performance of the Ryzen Threadripper 3990X and Radeon RX 5700 XT within that workstation has evolved.
