AMDGPU-PRO vs. Open-Source Gallium3D OpenGL Performance On Polaris Is A Very Tight Race

Xonotic is one of the few tests where the open-source driver performance lags greatly behind the AMDGPU-PRO driver.
With OpenArena the frame-rates were close to the same between the two driver stacks, but with OpenArena allowing us to tap the frame timing information we see that there were higher spikes in latency when using RadeonSI Gallium3D.
