I installed gpu and ran all that night, call of duty, high settings 120-150 FPS consistent even showed in amd software.

last 2 days 80-130 fps average of 90. No settings change.

what could cause this?

Does your computer seem to be overheating in any way?Overheating can cause a massive drop in performance.
It’s possible, I will check this evening, I mentioned that to a friend s about putting a big fan in front of it until I can get a bigger box and better cooling. I thought maybe bottlenecking but it doesn’t see like that.
