AMD Ryzen 7 high CPU usage, application freezes

I think it works a little bit better, no rockets but satisfactory.
Ok for now I have added amd-pstate it was quite hard, but it is.
I don’t have CPPC option in my BIOS.

cpupower frequency-info

analyzing CPU 8:
  driver: amd-pstate-epp
  CPUs which run at the same hardware frequency: 8
  CPUs which need to have their frequency coordinated by software: 8
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 400 MHz - 4.37 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 400 MHz and 4.37 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 1.40 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: no

But still

modprobe amd_pstate

modprobe: FATAL: Module amd_pstate not found in directory /lib/modules/6.4.6-1-MANJARO

and now that line you mentioned
