Radeon Linux OpenGL Driver Continues Giving Its Best Against Windows 10

Now we hit the game tests where on Linux they are mostly Direct3D-to-OpenGL game ports by Feral. First up with Deus Ex: Mankind Divided, the RX Vega 64 on Linux was running at 75% the speed of Windows while the RX 580 came in similarly. What's unfortunate about this case for Deus Ex: Mankind Divided at 1080p with ultra quality settings is it was the difference between this game being playable or not. On Linux the average FPS is only 58 and bottomed out at 29 compared to on Windows 10 where its average frame-rate was at 77 and a minimum of 60 FPS -- yes, the minimum Windows frame-rate being higher than the average frame-rate on Linux.... In 2018, with the latest drivers on both platforms.

GRID Autosport is a lighter game and this racing title could at least deliver playable frame-rates / always 60+ FPS on the RX Vega 64 while on Linux. Here both the RX 580 and RX Vega 64 came in at about 81% the speed of the Windows game performance.

Shadow of Mordor is usually an interesting OpenGL game benchmark and has worked on RadeonSI for a while, but when testing on Linux, unfortunately it has regressed in Mesa... Currently the game hangs on the loading screen:
