V4 lagging

Just updated to V4 and noticing right away that it is struggling to playback or scrub through preview even before doing anything with 60fps H265 file. Haven’t tested any prores or H264 since I JUST updated. V3 was smooth.

No reason for this to lag this bad. And I mean bad bad lag in the timeline.

Actually, how do I revert back to V3. This is EXTREMELY bad. It’s so bad I can’t even get a playback on the preview to make sure it worked.
