Greetings @Ivan3z
Do you run any sort of software in the background like Afterburner? If so, try turning that off, restarting, and test again. I’ve had this same scenario while using it. If not, I’d go into a more detailed look at your CPU and see if it’s something like 1 or 2 cores working at 100% while the rest are unused. (Depends on which CPU you run as to how many it could be with performance cores vs efficient cores)
