Radeon Software 18.50 vs. Linux 4.20 + Mesa 19 Benchmarks On The AMD RX 590
Rise of the Tomb Raider, a Vulkan-powered Linux game port, saw similar performance between the competing AMD Linux graphics drivers.
Talos Principle was another game where the OpenGL performance easily sides with RadeonSI but the Vulkan performance was very close between the drivers.
Team Fortress 2 was faster on RadeonSI, to no surprise at this point.
