After Effects 2022 Really slow to preview.

I'm running an RTX 3080, 32GB RAM, intel 10700KF, and a 1TB M.2 SSD.
I'm trying to edit a 26 minute video I screen recorded. It's 1440 (2560x1440).

Preview is moving at about 1 second every 3 seconds and then once it gets to about 2.25 minutes, the green line clears all progress starts over where it's at. This process repeats every 2.25 minutes for the entire thing.

I've got "Cache before Playback" enabled, 30 fps, reesolution @ a quarter.
Is this a caching issue? I've cleared c$\user\AppData\Local\Temp, and rebooted.

Task manager reports 83% Memory usage, and GPU reports spikes from 30% - 70% consistently.

It's been a while since I used AE, and this is my first time using it on this machine. I don't remember it being this slow, but I don't think I was trying to edit this resolution or length before either. Given my variables, is this expected performance? 

Of note: I used OBS Studio to record, then converted it to MP4 via VLC before importing into AE.

Tips?
