The dpm performance level can be changed to push the memory and GPU frequency to the highest levels (maximum performance).
NOTE: The default is auto, but this may result in some lag at some points while the GPU ramps up performance.
Set High Performance
To set max performance:
echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level
Set Low Performance
To set low performance:
echo "low" > /sys/class/drm/card0/device/power_dpm_force_performance_level
Set Auto Performance
To set Auto performance:
echo "auto" > /sys/class/drm/card0/device/power_dpm_force_performance_level
Check the Existing Performance Level
cat /sys/class/drm/card0/device/power_dpm_force_performance_level
