Metal sounded like a good idea to get in the emulator but frankly I
underestimated just how experimental and not ready it was.
From my write up in the Discord:
```
As is, Metal supports only a few games.
The games it does support freeze on first use of not playing them via Vulkan, because shader translation is broken.
So you need to use a dirty hack to not delete all your shaders.
Not to mention it breaks many games via MoltenVK because of changes to the shared GPU code.
Merging Metal seemed like a great idea, because of the few games it does support.
But I don't think it's worth it. Many of the games it breaks via MoltenVK *don't work via Metal*.
Which effectively makes current Ryubing worse for Mac users than Ryujinx 1.1.1403.
I think what I'm gonna do is revert Metal, and reopen it as a PR. That way, you can still take advantage of the Metal backend as is, but without making other games worse with no solution.
```
For what it's worth, the shader translation part could at least be
"fixed" by always applying a 30ms delay for shader translation to Metal.
That being said, that solution sucks ass.
The MoltenVK regressions are even worse.
I hope this is not a let down to the Mac users. I hope you realize I'm
reverting this because you're actively getting a worse experience with
it in the emulator.
ARMS: Tested every character and every Map, played a cup as well. It
works flawless in my testing. (If it freezes, that is caused by the
Hypervisor, not Metal. You need to disable the Hypervisor for this game)
Luigi's Mansion 2 HD: I tested every world a bit and had no issue. Isaac
said he specifically worked on it as well
Following games were flawless in my testing, but I only tested earlier
parts of the game so far, a late game part might have an issue,
therefore I will further test these in the future:
- Astral Chain
- Bayonetta Origins
- New Pokemon Snap
Added some more titles to the RPC environment
-Brawlhalla
-Minecraft
-Risk
-Stardew Vallet
-Valkyria Chronicles 4
-Super bomberman R
-Arcade archives Super mario bros
-Divinity Original sin 2 DE
-Monopoly
-titan Quest
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.
