Radeon Software 20.10 vs. Upstream Linux AMD Radeon OpenGL / Vulkan Performance

But for the newer Unigine Superposition it's much more of a fight between the AMD OpenGL driver and Mesa.

The newer Mesa tended to perform better with the Xonotic game.

ACO helped deliver more wins for RADV when it came to the Basemark benchmark.

When looking at the geometric mean of all the Vulkan tests where all configurations could be tested (ACO included), here is a look at how the Radeon Software 20.10 Vulkan performance either matches (RX 590) or slightly ahead on Navi and Vega but when flipping on the ACO back-end the Mesa RADV driver easily blows it out of the water. And then for the OpenGL tests, it was nearly a landslide victory for RadeonSI.
