Windows 10 vs. Ubuntu 16.04 Graphics Performance With Radeon Software, AMDGPU-PRO, AMDGPU+RadeonSI
With the Talos Principle, the Direct3D 11 renderer on Windows was by far delivering the best performance. The OpenGL performance between Radeon Software and AMDGPU-PRO was about the same as was the Vulkan results. However, coming in a distant last was the Linux 4.7 + Mesa 12.1-dev numbers on this Radeon R9 Fury graphics card.
The Dota 2 OpenGL performance was also similar between Windows and Linux.
The Vulkan performance was also similar, albeit no open-source AMD Vulkan driver support yet.
