Windows 10 vs. Linux 4.15 + Mesa 17.4-dev Radeon Gaming Performance
Lastly is the Total War: WARHAMMER game on Linux and Windows.
At 1080p with ultra image quality settings, the numbers unfortunately weren't landing on a high note for Linux.
While at 4K, similar to the Shadow of Mordor 4K results, the RX 580 was performing similarly under Windows and Linux but not really a playable experience. The RX Vega 64 meanwhile was ten frames lower on Linux than Windows and that put it under a 60 FPS average.
The OpenArena / Xonotic / Unigine results as we've shown since a few months ago now perform basically the same or better on Windows and Linux. Last year and going back further, even in those tests RadeonSI OpenGL wasn't outperforming the Radeon Software driver on Windows, but that changed with all of the improvements made this year to the open-source Radeon Linux graphics driver stack. But unfortunately with the popular Linux game "ports" that are often going from Direct3D to OpenGL or now Vulkan, unfortunately, their performance is still having a significant performance difference between operating systems.
