Dota 2 7.00 - Mesa 13.1-dev: OpenGL RadeonSI vs. Vulkan RADV
Written by Michael Larabel in Linux Gaming on 16 December 2016. Page 3 of 3. 13 Comments

When upping the game to 1920 x 1080, the Vulkan performance was now lower across the board over the OpenGL results. With the higher-end graphics cards (RX 470 / RX 480 / R9 Fury) the Vulkan performance hit was much less than the lower-end graphics cards struggling.

Lastly when testing Dota 2 7.00 at 4K, the Vulkan performance remained lower across the board. The R9 Fury with Vulkan was running at 74% the speed of the OpenGL RadeonSI performance while the RX 480 was at 80% the speed with Vulkan.

That's the latest Dota 2 7.00 Linux performance data for those interested as well as the newest RadeonSI vs. RADV performance on Mesa 13.1 Git with Linux 4.9. Stay tuned for Talos Principle OpenGL vs. Vulkan results along with a large OpenGL end-of-year comparison next week.
