NVIDIA GeForce GTX 1080 Ti: Windows 10 Creators Update vs. Ubuntu Linux Gaming
Even with using the NVIDIA proprietary drivers, Deus Ex: Mankind Divided with D3D11/D3D12 remained much faster than the OpenGL version of this game on Linux. This difference is largely due to the quality/overhead of the Linux port and unfortunately there is no Vulkan renderer for this game, at least not at this time.
Even with the GTX 1080 Ti at 4K on low quality settings, the Linux results were under a 60 FPS average.
GRID Autosport also is much faster on Windows 10 over Ubuntu Linux due to the quality of this Linux game port by Feral Interactive.
Shadow of Mordor's Linux performance was a bit closer to Windows 10, but still there is significant overhead in the Linux port.
The Talos Principle is supported well under Linux by Croteam. These results with the GTX 1080 Ti show similar OpenGL and Vulkan performance between the two operating systems but the D3D11 renderer for this game on Windows 10 remains the fastest.
