Progressive FPS Drop On Pc. GPU utilization capped?

For some reason, the game has started slowly decreasing in frames per second on my Forza Horizon. Regardless if I am in the menu or driving, the game keeps getting lower and lower in FPS. I am on PC using the xbox game launcher. I have the in game fps counter and GPU usage displayed and it appears to show my GPU usage being stuck between around 20%-30% even though I used to be able to play the game at max settings with upwards of 144 fps no problem. This issue only started today for me but one of my friends got the game a few days ago and it started happening to him about 2-3 days ago. has anyone been experiencing the same issue?

I started having the same issue over the last few weeks. 7800x3d, 32gb of CL30 6000mhz RAM, RTX 4080, and somehow the best I can do is 20-30% utilization and similar frames. It happened once about a month ago and a reset of the game fixed it. It has progressively gotten to the point that nothing works to fix the issue.
