fwiw metald3d logs a couple of error messages like this, taking a quick look at the renderdoc it seems like this is the issue:

Failed to create pipeline state: Error Domain=AGXMetal13_3 Code=3 "Fragment input(s) `user(texcoord6)` mismatching vertex shader output type(s) or not written by vertex shader" UserInfo={NSLocalizedDescription=Fragment input(s) `user(texcoord6)` mismatching vertex shader output type(s) or not written by vertex shader}, vs=81395087550621614903112759022732522635024016920034294967295429496729500,fs=8125458665587274230746641964946232789990602801,gs=,ds=,hs=, marking PSO(133) as no-op

Intel GPU on Windows OS also has this problem Nvidia works well

Finally got around to looking at this, game is extremely broken and uses incompatible shaders and somehow expects this to work when it really shouldn't.

Fixing this is technically possible by rewriting the fragment shader at runtime, but it's difficult and not a high priority at the moment.

This sounds like it would be a game-specific hack type of thing, yes?
