Mesa 18.0/18.1/18.2 RadeonSI + RADV Benchmark Comparison With Radeon RX 580 / R9 Fury / RX Vega 64

There's not much to see these days out of Tesseract.

Unigine Superposition with low quality settings does see faster RX Vega 64 performance on Mesa 18.2.

The Xonotic OpenGL game fluctuated very little with the latest RadeonSI Mesa builds.

Mad Max on the Polaris and Fiji graphics cards were faster now with Mesa 18.2 and for this apparently CPU-limited configuration was in line with the Vega RADV numbers.

There's certainly less fluctuations in the RadeonSI/RADV performance this year than we saw last year when particularly the RADV driver was still playing catch-up with the official AMD Vulkan Linux driver and RadeonSI finishing its triumphant performance optimizations over the past roughly two years in catching up to the proprietary OpenGL driver performance. But in some games it still certainly pays off to upgrade to the latest Mesa series or even Git, but in some cases, there are also regressions.
