1080p Linux Gaming Performance - NVIDIA 415.22 vs. Mesa 19.0-devel RADV/RadeonSI

Batman: Arkham Origins is the newest Batman game running fine via Valve's Steam Play for handling the Windows version on Linux. The RX 580/590 Polaris cards were running noticeably slower than even the GeForce GTX 1060 at 1080p.

Meanwhile with the BioShock Infinite game at 1080p with ultra quality settings the tested cards were all well above a 200 FPS average. The RX 580/590 were hovering around the GeForce GTX 980 performance which was well below the tested Pascal cards.

Deus Ex: Mankind Divided is back to working with the latest Mesa 19.0-devel RadeonSI state. Here the RX 590 performance was around that of the GTX 1060.

Dota 2 is just CPU bound at 1080p even with the Core i9 9900K.

Dawn of War III with Vulkan didn't see any scaling between the GTX 1070 and GTX 1070 Ti at 1080p. The RX 580 to RX 590 performance difference was only a few frames and straddling the GTX 1060.
