RadeonSI's Mesa Shader Cache Can Be A Big Help To Modern Linux Games
Dota 2 with its OpenGL back-end appeared to be a bit faster with the shader cache enabled.
While the run-time was a little bit faster.
DiRT Rally appeared to have minor benefits in performance too when using the RadeonSI shader cache.
With HITMAN, the frame-rate performance was unchanged during testing but the benchmark did run quicker, indicating shorter load-times.
