Question Strange GPU And CPU Usage

Jul 2, 2020

I am in a weird situation with my CPU and GPU. The usage for both devices can be very strange depending on the game. Sometimes my CPU usage is normal, but the GPU usage will fluctuate from 99% down to 10%. And other times my GPU usage will be normal, but my CPU usage will be very low at around 40%. This causes low fps and lag spikes in games. I also noticed that when I change my graphic settings from low to epic, there is no visible change in FPS. Now, I know this is a sign of a CPU bottleneck, but that doesn't seem to be the case because both my CPU and GPU are supposed to work well together. Drivers are up to date, Temperatures appear normal.

My specs:
GPU: RX 580
CPU: I7-7700k
RAM: 16 GB
Motherboard: MSI B250M BAZOOKA
HDD: 931GB Western Digital WDC
