AMDGPU+RADV Linux Gaming On GCN 1.0/1.1, 25-Way Warhammer II GPU Benchmarks

With Feral Interactive's modern Linux game ports that rely upon the Vulkan graphics API for rendering, the company usually lists the Radeon R9 285 as the minimum requirement. That's generally because the R9 285 "Tonga" is the first graphics card officially supported by the AMDGPU kernel driver, which is necessary for RADV Vulkan driver support, but with non-default options it's possible to get AMDGPU+RADV working on GCN 1.0 Southern Islands and GCN 1.1 Sea Islands graphics cards. Here are some benchmarks of that experimental GCN 1.0/1.1 Vulkan support using Feral's newest Linux game port, Total War: Warhammer II, in a 25-way AMD/NVIDIA graphics card comparison for Linux gaming.
