Mesa 19.0 RADV vs. AMDVLK 2019.Q1.2 vs. Radeon Software 18.50 Linux Vulkan Performance

Thrones of Britannia had a slight advantage with the Mesa RADV driver particularly for the Vega GPU while the Polaris performance was much closer between these three Linux drivers.

Warhammer II was also performing the best with Mesa 19.0 RADV and actually be a measurable difference.

The performance between the open-source Mesa-based RADV driver and the official AMD driver options of AMDVLK (open-source, built against LLVM) and Radeon Software PRO (similar to AMDVLK, but still using the proprietary compiler for now) remains quite mixed. In some titles the Radeon Software Vulkan driver still has its advantages particularly for Vega, but it's to a lesser extent these days compared to months ago when it often had some pronounced leads thanks to its quicker ramping up of Vega support. With Mesa 19.0 built against the AMDGPU LLVM 8.0 back-end, the RADV performance is quite good and for newer Feral titles as well as Steam Play titles with DXVK is often leading or at similar to the AMD driver. This final graph is of the harmonic mean of all the FPS data from this Linux gaming benchmarking. So the situation is incredibly competitive now between RADV and AMDVLK/PRO for both Polaris and Vega though later this year with Navi will likely be the situation again of the official Vulkan drivers initially having better performance and support than RADV until the "community" developers are able to catch up with their support.
