Mario Kart 8 Deluxe and Deltarune got tested by Isaac with help from
Peri previosly (His video: https://www.youtube.com/watch?v=GEVre_0ZVUg
)

Captain Toad, Cuphead and Animal Crossing I tested myself (side-by-side
Video comparison: https://youtu.be/auNS9MmZMPI )

Additional information:

Cuphead has flickering issues with certain UI elements on Vulkan via
MoltenVK. Metal fixes those and introduces no new issues, according to
my testing.

Animal Crossing is accurate, except for it having broken backgrounds in
interiors, causing them to appear as white instead of black. This is
caused by a hardware level sampler bug, that isaac never got to find a
workaround for.
However, this issue happens with Vulkan via MoltenVK as well, both Metal
and Vulkan have this issue, therefore Metal shouldn't have any downside
compared to using Vulkan in this game.
