Radeon RX 560/570/580 vs. GeForce GTX 1060/1650/1660 Linux Gaming Performance
Strange Brigade has a known issue currently with RADV / Mesa Vulkan WSI but a workaround is available to avoid the vsync-like behavior and a proper fix will hopefully be coming soon. Anyhow, Strange Brigade is another Steam Play game and can easily run with the tested cards at 1080p sans the RX 560 coming in short at ultra quality settings.
With Thrones of Britannia at 1080p medium settings, the RX 560 squeezed past a 60 FPS average while all of the other cards could run more comfortably. The RX 580 was coming in just behind the GTX 1060 for this Feral-ported game.
With high quality settings, the GTX 1060 remained slightly ahead of the RX 580.
