I am running Zorin OS 16 on an Asus laptop (Ryzen 7 5800H) and using a gnome extension to measure clock speed and I see that the CPU is maxing out at 3.6Ghz, not going beyond 4Ghz (specs say that max turbo boost is 4.4Ghz)
Is there a performance setting? I saw some settings on Pop OS though.
What I was trying to say is that the OS might be limiting the CPU to ensure battery drain does not happen quickly - the more CPU power is used the quicker the battery will drain.
