A change queued up last week by AMDGPU driver maintainer Alex Deucher will now default to the fullscreen 3D workload profile for discrete GPUs. AMD APUs with integrated graphics will continue to use the default “bootup” power profile but discrete graphics cards will be running in the “fullscreen 3D” power profile by default.
I believe it’s
cat /sys/class/drm/card0/device/pp_power_profile_mode.There’s also the
power_dpm_force_performance_level.
