Marek Olšák, a long-time AMD Linux graphics driver expert who joined Valve earlier this year, has had his latest work merged for Mesa 26.2. Olšák, now focusing primarily on the RADV Vulkan driver rather than RadeonSI Gallium3D, landed a significant overhaul to the variable rate shading (VRS) code. This update is reported to "in some cases can double the performance" according to Phoronix. The changes improve how VRS is handled within the RADV driver, impacting performance in scenarios where VRS is utilized.
