Windows 10 vs. Linux 4.15 + Mesa 17.4-dev Radeon Gaming Performance
Now onto the more modern and popular Linux games but titles that were "ported" from Windows to Linux and in the process going from Direct3D to OpenGL (or Vulkan). First up is Deus Ex: Mankind Divided that is using OpenGL on Linux and has received a fair amount of optimizations this year by the RadeonSI Gallium3D driver for better performance.
While Deus Ex: MD has received a lot of optimization work with RadeonSI in past months by both AMD and Valve developers, the Radeon Linux performance remains significantly lower than what's found natively for this game on Windows 10 Fall Creator's Update.
When pushing the game with ultra image quality settings, the Radeon Linux performance was still losing out by similar margins. The peak frame rates on Linux tended to be even less than the average frame-rates on Windows while the minimum frame-rates on Windows tended to be higher than the Linux FPS averages.
Next up is F1 2017, the most recent Linux game port by Feral Interactive. This also marks the first Vulkan-only Linux commercial game port while Windows is using Direct3D. Sadly, even at 1080p and with low quality settings, the Radeon Vulkan Linux performance was noticeably slower than Windows.
When upping the test to ultra high image quality settings at 1080p, both graphics cards still delivered playable frame-rates on Linux but they remained noticeably lower than the Windows 10 performance on this Core i7 8700K system.
