Intel Graphics With Linux 6.6 Adds Tuning Knobs That Can Yield 10~15% Better Performance
With new i915 driver code ready for the upcoming Linux 6.6, new threshold tuning around the RPS (cited as both Render P-States and Requested Power States) for some Intel graphics hardware and in some games can yield around a 10~15% boost to performance.
Back in April I wrote about some Intel graphics driver patches allow for tuning up to 10~10% better performance. That work came from Google Chrome OS engineers around allowing the Intel RPS up/down thresholds to be configured by user-space. Google engineer Syed Faaiz Hussain raised the issue that they experimented with the Intel RPS tuning and were able to manage up to 15% better performance. With Counter-Strike: Global Offensive with OpenGL was a 14.5% boost, CS:GO with Vulkan was 12.9% faster, and Civilization VI with OpenGL was 11% faster.
