Low FPS with Low GPU Load, need to Restart for Fixing.

[Opest7999]

Hello,
I have a problem. My Problem are my low FPS in Games, after starting my computer every game has fps issues. This mean low fps and fps jumps. After restarting the hole computer, the issues are gone. This is even reproducible. If I restart the PC directly after booting up, I have no problems. I Have no idea what kind of Problem this could be.

Specs:
CPU: AMD Ryzen 3600
GPU: AMD RX6600
RAM: 16GB DDR4 2400mhz

Tested Games:

Apex Legends

Before Restart
CPU: 50%
GPU: 90-50%
FPS: 48-140

After Restart
CPU: 40%
GPU: 100%
FPS: 144

Wolfenstein The New Order

Before Restart
CPU: 10%
GPU: 100%
FPS: 9-27

After Restart
CPU: 40%
GPU: 80%
FPS: 60

Specs make no sense for me. Anyone an Idea? Drivers are actuall, Problem still there after clean OS Installation

did you install the correct drivers? from oem mfg or mobo site?

windows update never grabs the correct ones

you cannot look at cpu usage to see if its cpu bound, games can not use all cores all the time, and windows does a good job at balancing core loads

do you often use default shutdown (sleep/hibernate), or is that disabled so it actually does a clean boot every time?

Looks like CPU bottleneck due to slow RAM.
Or some app eating resources.

I shout down the PC every evening. Use no clean boot.

by default, 'shutdown' uses hibernate
which is really dumb

did you disable hibernate?
run command as admin, powercfg -h off
reboot
