[PC] 100% CPU usage

I closed every single thing on my PC and still Forza Horizon 4 runs my CPU into overdrive. It overheats my CPU and only uses 20% of my GPU… I need a fix because I cannot play Forza like this. With this happening My loading times when switching cars averages at around 8 minutes. My turbo clock is thermal throttling because of Forza isn’t using any of my GPU and is fixated on throttling my CPU. I still have 100+ FPS on ultra however.

Are you maybe using the onboard gfx instead of your gfx card?

Yeah I am sure cause my monitor is plugged into the GPU not the Motherboard.
