Multi-Cam Stuttering Horribly at Lowest Res Possible

First, hardware:

I'm editing in DNxHD codec in 4K. I don't know what happened but in the last week, my playback while editing together a very simple 3 cam shoot has become stuttering to the point where Premiere crashes randomly. I have the playback set to 1/16 res and it's still horrible. I've already checked my audio hardware, cleared my cache, rolled back to 22.0 and nothing is improving. I was working on this same file last week at full res with 0 issues.
