Extreme lag (scrub and playback)

[Team5C2A]

Hey there, was recently forced to update to Premiere 23 due to work updates, and the lag/stuttering when i scrub through timelines (which were fine before in Premiere 22) is killing me. My playback has also been effected (stuttering playback) but not to the same extent as scrubbing. 

I'm working off of a iMac 2019, OS Big Sur.

Any solutions to this? Am I missing some setting that got switched on when I updated?

Actual result - Since updating to Premiere 23 I haven't been able to scrub in real time, and playback is also affected.
