RADV Radeon Vulkan Driver Is Still A Better Bet Than AMDVLK In February 2018
When running Mad Max at 4K with low image quality settings, the RADV win was narrower but still siding with this Mesa-based Vulkan driver than the official Vulkan driver.
While lastly when really pushing these GPUs hard by high quality settings at 4K, the RADV vs. AMDVLK performance was very similar and in some cases siding slightly with AMDVLK.
