Apple Silicon: Add Steam Native Gaming Support for Apple Silicon

[NripeshN]

Steam on Apple Silicon, baby! Let’s configure native Steam gaming support so users don’t have to rely on workarounds like MicroVMs. Steam’s Proton layer can handle most of the heavy lifting for game compatibility.

Ideas/Problems:

• MicroVMs are a neat idea, but for casual gamers, having native Steam support is a much better experience.
• Apple Silicon GPUs are powerful, so let’s make sure we use them efficiently for gaming.
