Final Fantasy IV : The complete collection

[Cutsman]

After just completing FF3 with no issues, I'm having an issue with FF4 where the video stutters / frame drops for about 1-2 seconds every 10 seconds. It's very odd. The game seems to look and play fine otherwise. I've tried a ton of variations of settings and nothing seems to work. Any ideas?

Edit: After playing with it some more, I have discovered that changing it from CPU core Dynarec to IR interpreter makes it go away, but adds an annoying audio skip whenever going into a doorway (when loading occurs, I assume).
