MetalSharp
v0.59.5 — Apple Silicon, macOS 14+

Windows games. Native Metal. Your Mac.

MetalSharp runs your Windows Steam and GOG library natively on Apple Silicon — a custom Wine 11.5 runtime, per-game launch routing, and MetalFX upscaling, all behind one clean interface.

Why MetalSharp

A translation pipeline, tuned per game.

Not another wrapper. MetalSharp builds its own runtime and picks the right graphics backend for each title — automatically.

MTSP Routing

Automatic pipeline selection based on compatibility data and developer testing. DXMT, VKD3D, D3DMetal, or Mono/FNA — chosen per game, not per guess.

Default rules for tested games

MetalFX + msync

Sidebar toggles for MetalFX upscaling (1.50 / 1.75), msync synchronization, and controller input shims — applied on next launch, no config files.

Sharp Library

Beyond Steam: import standalone Windows programs, installers, and launchers — and download & play GOG games directly through the Sharp library.
