Shader clock and fps directly after a boot
everytime I start RocketLeague the first time after a boot I have some kind of micro stuttering. This happens with my RX550 and on a Vega 56.
A workaround is to set power_dpm_force_performance_level to "high".
Setting it back to "auto" on the RX550 makes the stuttering return. Doing the same thing on the Vega 56 not and the stuttering is gone until the next boot.
I'll attach three screenshots that display the shader clock and fps via gallium hud. One directly after a boot, one with performance_level set to "high" and one after resetting it to "auto". All screenshots were made with the Vega 56 and Mesa 18.2.0.
