Performance with Mesa / radeonsi in Wine 2.18 (with needed patches applied)

Max settings, hairwokrds off.
Resolution: 1920 x 1200.
Average framerate: 40 fps.
GPU: AMD Sapphire Nitro+ RX 480.
OpenGL renderer string: AMD Radeon (TM) RX 480 Graphics (POLARIS10 / DRM 3.18.0
/ 4.13.0-1-amd64, LLVM 5.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.0-devel
(git-e5e93c727f)

As you can see, GPU is fully utilized.
