I'm trying a couple of potential fixes and I did this one first. Up next, rolling back drivers.
UPDATE 3: As per /u/deylath on reddit, I turned off Origin gamepanel/Origin in-game. I noticed better animation syncing, but that seems to be all that was changed. The first tutorial battle (I'm testing with my old saves wiped still) still experiences incredible lag, maybe about a half-speed fps drop to what I could run before (previously to this issue, battles ran smoothly, no lag). And the following cinematic finds itself completely out of sync with the sound again with fps drop still happening. Partial fix?
