Radix sort seems buggy on Mac M1 and iOS #226

Has anyone managed to get this 3DGS renderer to work on iOS lately?

I am running the project on a Mac Mini M1 2022 and building to iOS18 for iPhone 13 Pro, and from what I am seeing, rendering works properly when I disable the radix sort, but as soon as I put it back in it starts glitching and never seems to sort properly (both on Mac editor and on iOS build).

From what I read here and there metal doesn't like large threadgroups so I tried to fiddle, with that with no success. Am I missing something?

I'm running Unity 2022.3.62 with Builtin renderer, and a test scene with around 500k splats.
Any help appreciated
