Link's awakening I have played through most of the game with 0 issues.

In LEGO City undercover I have played multiple missions and explored the
map, I was unable to spot any issue. Except shadows flickering
sometimes, but that seems to happen on Vulkan and the PC version as well
and is propably normal.

Bayonetta seems to work flawless so far.

In Fast RMX, some tracks have flickering issues, like the second track
of the first cup. This happens on Vulkan as well.

Mario Bros. Wonder has following issues:

Overall issues:
- Sometimes there is short white flickering/artifacts, but they happen
on Vulkan as well.

Metal specific issue:
- In 2 underwater levels, a specific location causes a FPS drop not
present on Vulkan. But this is very minor and on all current M chips you
get on average better FPS with Metal (On my M3, there are occasional
drops that are worse with Vulkan), reducing stutter quite noticeably,
which is why I think it should get added to auto regardless.

- Isaac mentioned there is a issue in level 2, where the flowers singing
desync somehow. However, I was after lot of testing unable to replicate
this issue at all. More testing could be useful.
