Radeon Software 18.10 vs. Mesa 18.2 RADV/RadeonSI Benchmarks

Under the open-source Tesseract game, the Mesa RadeonSI Gallium3D driver was running much faster.

Unigine Heaven was a rare exception where this OpenGL benchmark was faster on the PRO driver stack than RadeonSI.

While in the newer Unigine Superposition benchmark, Mesa 18.2 was faster than PRO.

Xonotic was faster on RadeonSI by quite a difference.

The X-Plane 11 flight simulator was also running faster with Mesa 18.2 rather than the PRO driver.

Rise of the Tomb Raider worked fine with Mesa 18.2 but did not with Radeon Software 18.10. There was the recent workaround in the AMDVLK repository for fixing the official Vulkan driver for this latest major Linux game release, but it doesn't appear to have made it for the 18.10 release stream.

In the Vulkan tests there still is a healthy competition taking place between RADV and the official Vulkan driver, but for the OpenGL games/benchmarks, RadeonSI was dominating over the PRO closed-source OpenGL driver. As we have seen over the past year, RadeonSI has become super competitive with continued driver optimizations where it was winning in all the tests we ran today for OpenGL games/benchmarks with the exception of Unigine Heaven.
