AMDGPU-PRO 16.50 vs. RadeonSI Git: Tomb Raider, Shadow of Mordor, WARHAMMER & Deus Ex
First up is the Tomb Raider Linux game port that was released for Linux back in April. Tomb Raider does have some CLI switches for benchmarking but unfortunately doesn't work for the quality controls properly, thus has to be set manually.
Interestingly, the Mesa 13.1-dev performance is much better than AMDGPU-PRO 16.50 with the tested Polaris/Fury graphics cards. There were no visible rendering problems with either driver stack and from a cursory examination had about the same rendering quality with the applied settings. When at low quality settings, there wasn't much of a difference between the RX 480 and R9 Fury.
With high quality settings at 1080p, the RadeonSI Gallium3D driver via Mesa 13.1-dev continues performing much better than the AMDGPU-PRO 16.50 driver stack. Again, the rendering appeared fine on both drivers.
Tomb Raider is very much playable with newer AMD graphics cards on the RadeonSI driver stack.
Even at 4K, Tomb Raider is playable with a Radeon RX 480 or R9 Fury on the fully open graphics driver stack.
