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

With the Tesseract open-source OpenGL-powered game, the AMD proprietary OpenGL driver was much slower than Mesa.

Thrones of Britannia hit crashes with the Radeon Software driver while aside from that the other takeaway is the much higher performance still with ACO.

Unigine Heaven remains one of the few Linux OpenGL test cases where the proprietary driver performs much better than RadeonSI.
