The Latest Talos Principle Vulkan RADV & OpenGL RadeonSI With Mesa 13.1-dev

This week I posted many Dota 2 7.00 benchmarks with different AMD graphics cards while testing Mesa 13.1-dev + Linux 4.9 with both the RADV Vulkan driver and RadeonSI OpenGL driver. Here are some tests of the latest The Talos Principle build while comparing those OpenGL and Vulkan numbers.

This past week Croteam pushed their Vulkan enhancements to stable rather than being in public beta, so that plus the latest Mesa 13.1-dev code makes for some fun OpenGL vs. Vulkan benchmarking as we get close to the end of 2016. The Talos Principle test profile was also recently updated.

Unfortunately, this 64-bit Talos Principle still doesn't run ideally on the open-source stack but even with a 1080p resolution was rather slow for the tested RX 460, RX 480, and R9 Fury graphics cards with the test profile's configuration used. The Talos Principle also didn't want to run with RADV on the R9 285.

With The Talos Principle though we see the OpenGL vs. Vulkan performance being much closer than with Dota 2:

In fact, at 1080p the RADV Vulkan performance was faster than RadeonSI for the Radeon RX 480 and by just a few frames for the RX 460 and R9 Fury.

Those wanting to compare their own system's performance in the same game configuration as used in this article can simply install the Phoronix Test Suite and simply run phoronix-test-suite benchmark 1612175-TA-TALOSGLVU22. And check out this week's Dota 2 VLK/OGL benchmarks if you didn't yet have a chance to see all those numbers.
