I think if found the solution.
The “too many” temporal samples” error is the culprit here as for some reason it speeds up everything from material time to BP tick time, physics and as it appears particles as well.
The best fix I found was to set my Motion Blur settings in the Post-Process Volume to their default values haven’t tested others, but them being set to 0 messes everything up. Depending on your setup these might be in your cine camera and etc. but from my findings motion blur seems to be culprit here.
