Bounding Box slowdown...
Chapter 3-4 (Fort Francis)

Chapter 7-2 (Underwhere Road)
- to 50%~ only when you met Dorguy the First. No slowdowns on meeting second or third Dorguy.
- to 10%~ when Bowser uses his fiery breath to ignite the torches to temporarily light up in (two) rooms.
Chapter 7-4 (Grambi's Temple)
- to 65%~ when you use Luigi's special move (super jump) anywhere in the area where there are an epic fight between two armies in front of the temple.

Is the issue present in the latest stable version?
If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)
[First broken version number here (if applicable)]
If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer
[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]
What are your PC specifications? (CPU, GPU, Operating System, more)
MacBook Air (M1, 2020)
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

For M1 users, this has been fixed (or as fixed as it'll ever be, translation layers will always have some trouble with the kind of CPU-GPU synchronization bbox requires) by the updated MoltenVK. Please rerun with a new dev build and verify this.
For Intel users, there's a second issue, which I've reported to MoltenVK. For the elevator scene on my Radeon Pro 5600M, frame rates have gone from 2.4fps to 9fps, but should be able to reach 16fps with that issue fixed, putting it ahead of DX11 and DX12 (but behind Windows Vulkan, Windows OGL, and Metal).
