Does Forcing "High" DPM Performance Help Out Your AMDGPU Performance? Written by Michael Larabel in Radeon on 7 June 2018 at 06:04 AM EDT. 14 Comments A premium patron recently asked about testing the open-source Radeon driver performance when testing the forced "high" dynamic power management state rather than the default "auto" mode. Here are some benchmarks. This is about forcing /sys/class/drm/card0/device/power_dpm_force_performance_level to high rather than auto, to ensure the GPU is bound to its highest performance state rather than dynamically changing performance states based upon
