TSR in 5.4+ breaks WPO effects by making them blurry & kills performance drastically

There’s something up with TSR history I think. Here’s an example of the blurry effect: https://www.youtube.com/watch?v=JbkPW9zejJY

It also kills performance.

Issue is non-existent in 5.3, FPS great.

Is there a way to disable TSR history or somehow go back to 5.3 TSR?
