The amd-pstate schedutil configuration also saw the worst integrated graphics gaming performance results.

Running with the performance governor or even using acpi-cpufreq ondemand led to the best performance-per-Watt for the Unvanquished open-source game.

With Xonotic the acpi-cpufreq ondemand governor led to being the outlier with lower performance than the other CPU frequency scaling configurations.

The schedutil governor here did well for delivering the best power efficiency with this open-source game.

For workstation visualizations with ParaView, the amd-pstate schedutil performance continued to disappoint on Linux 6.0.
