Intel vs. Radeon vs. NVIDIA OpenGL/Vulkan Linux Driver Performance

First up with Dota 2 we see the Intel Kabylake performance with Vulkan is on-par to their mature OpenGL driver, the RADV Vulkan performance coming up a bit short of RadeonSI OpenGL with the RX 480 and R9 Fury, and the NVIDIA Vulkan performance being faster than their OpenGL driver. The GTX 1060 ends up being much faster than the Radeon RX 480 with Vulkan.

Or if looking at the relative performance... NVIDIA's Vulkan performance is about 9~10% faster while the open-source Intel/Radeon drivers don't have such luck.

Mad Max with its Camp Hollow Point scene sees a huge performance boost with Vulkan RADV over RadeonSI while the Intel Vulkan performance is a few frames short of their OpenGL frame-rates. The NVIDIA driver meanwhile sees slightly better performance with Vulkan, but even its OpenGL results for the GTX 1060 come out well ahead of the Vulkan RX 480 numbers. With RADV Vulkan the peak frame-rates were lower than OpenGL but much higher minimum frame-rates -- with NVIDIA's driver, the peak frame-rates were still higher than the OpenGL maximum but the minimum frame-rates were close between the graphics APIs.

RADV is the big winner with Feral's experimental Vulkan support in Mad Max.
