Performance Issues

Noticed my framerate is super inconsistent lately. Temps and usage is fine. Some matches constantly sitting at 400fps and 70% gpu usage others sitting at 30% usage and sub 200 fps. Normally it seems to degrade over time. I have a very high end PC and nothing is thermal or usage limited. Graphics are all comp settings and have done all the tweaks I’ve found, even set the game to high priority.
Plenty of space on the m.2 SSD it is located on
No thermal throttling, highest temp was 60c
No errors under Windows Reliability History tool
Benchmarks show nothing wrong and other games run fine.
Computer is very high end and well cooled. Other games utilise my PC as much as it needs and consistently reach the FPS cap
I did make a post previously but wouldn’t let me reply.
Below is a pastebin of my dxdiag

You did this last time too, you didn’t link an unlocked file. They have no way to look at it because it’s behind a password.
