Windows 10 vs. Ubuntu 16.04 Graphics Performance With Radeon Software, AMDGPU-PRO, AMDGPU+RadeonSI

Tomb Raider was one of the few games that wasn't running with Linux 4.7 + Mesa 12.1-dev + LLVM 3.9 SVN, at least out-of-the-box. When comparing the Windows to Ubuntu 16.04 + AMDGPU-PRO performance, the Linux results were about half the speed of the Windows numbers. Of course, with NVIDIA hardware too there was a big performance loss in the Linux port.

For GRID Autosport, the RadeonSI Gallium3D driver wasn't working out-of-the-box and here is another Feral Interactive game port running much slower on Linux than the original game release on Windows.
