With the latest AMDVLK Vulkan driver improvements back to coming out on a weekly basis by AMD and Mesa 19.0 development progressing ahead of its feature freeze later this month, here is a fresh Linux gaming benchmark comparison of the AMD Radeon Vulkan driver options on Linux. Tested this round with a Radeon RX 590 and RX Vega 64 was the latest Mesa 19.0 development state for RADV, this week's new AMDVLK 2019.Q1.2 driver snapshot, and the Radeon Software 18.50 proprietary driver while running a slew of Vulkan-powered Linux games and DXVK.
