High end system not performing as it should

[jessan39]

So as the title says my high end system is performing very porly. I had no performance issues the first one and a half week I had the cpu.
Since I dont belive my cpu bottlenecks my gpu (nor the other way around) that much in any game. I have no idea what could cause this and therefore I am reaching out to others for help/advice.

Example game:
Assassin's creed odyssey
4k res
Ultra High: 66% gpu - 42% cpu - 25 fps
High: 63% gpu - 27% cpu - 30 fps
Low: 59% gpu - 29% cpu - 43 fps

1080p res
Ultra High: 52% gpu - 29% cpu - 35 fps
High: 43% gpu - 29% cpu - 43 fps
Low: 46% gpu - 34% cpu - 62 fps

Cinebench: ~2072 running around 4800MHz-5000MHz

A little more brainfcking. I had a ryzen 1700 before the i9 and that cpu performed better in games than the i9 is atm.

Specs:
CPU: i9 9900k @stock
GPU: evga 1080 ti ftw3 @stock
Ram: 16gb ddr4 @2933MHz
Game installed on hdd

Ask for more information if needed. Thanks in advance.

Did you:
-Update all drivers and windows?
-Check temperatures (with MSI Afterburner or HWInfo/Monitor for example?)

I did a clean windows install a few days ago, I check for bios and driver update daily.
I don't really know "normal" intel temps but cpu is around 60-77 under load and gpu at a toasty 70+.
