Low FPS and High CPU Usage on all games since last update

[megavolt]

I guess the new change is a change in scaling the cpu:

@megavolt

If the CPU frequency is scaled at 2000Mhz at this moment, then htop for example will show full load even if you can run it at 3100Mhz. It is a powersaving method to just request what the application needs.

With

lscpu | grep CPU

You can lookup whats your max and min frequency.
