Question High CPU Usage Gaming - I7-9700K

Jul 14, 2020
Hey, so I recently upgraded my build... Well by upgrade I mean built a new computer. During idle/browsing the web/doing basic tasks everything seems to be fine... The minute I open games such as Rainbow Six Siege/Call of Duty/Valorant/CS:GO my CPU usage just jumps to 100% yet the game runs perfectly fine without lag or issues and high FPS.

The only way I can seem to drop the CPU usage is by limiting my FPS. I've NEVER had this issue before now.

I guess my question is... Is there a reason for this?


Mobo: MSI Meg z390 Ace
CPU: i7-9700k
Cooler: Corsair H115i Platinum AIO
Ram: 4x 8gb Hyperx Fury
GPU: EVGA RTX 2070 Super
SSD: 2x WD 500gb
HDD: 2x WD Blue 1tb

Things I've tried

Updating BIOS
Updating/Downloading Drivers
Clean install of Windows
Decluttering all drives.
Scanning all files on all drives.

I appreciate all the help I can get.

Is the CPU pegged at 100% usage at all times?

Or is it just a spike and then it decreases?
At 100% at all times yet the game still runs perfectly at high fps without lag... Just means I can't run the likes of OBS to stream/record. The only fix I've found is limiting the FPS instead of leaving it to run free.
