Direct answers.
Compatibility, hardware & architecture.

Onism Play translates Windows system calls and graphics APIs to macOS primitives in user space. Compatibility depends on the title's anti-cheat mechanism (kernel-level anti-cheats like Vanguard or Easy Anti-Cheat in driver mode do not run in Wine), the DirectX version, and available translation backends (D3DMetal, DXVK, or WineD3D). Many AAA titles—including The Witcher 3, Cyberpunk 2077, Final Fantasy VII Rebirth, and Baldur's Gate 3—run smoothly with high frame rates.

An Apple Silicon Mac (M1 or later) running macOS 26 or later. We recommend 16 GB or more of unified memory for AAA titles because Apple Silicon shares RAM dynamically between CPU tasks and the Metal graphics pipeline.

No. Onism Play is architected strictly for Apple Silicon. It harnesses Apple Silicon's unified memory architecture, Metal 3 shading pipelines, Rosetta 2 x86-to-ARM64 user-space instruction translation, and Apple hardware-accelerated media blocks.

Games requiring Windows kernel-mode drivers (Ring 0 anti-cheat systems like Riot Vanguard, BattlEye kernel mode, or EA Anti-Cheat kernel driver) cannot execute inside Wine prefixes on macOS. macOS kernel integrity protections prevent foreign kernel drivers from loading. Games with user-space anti-cheat or DRM-free titles run without issue.

No. Apple's Game Porting Toolkit and D3DMetal runtime are proprietary Apple software licensed under Apple Developer Terms. To respect Apple's intellectual property boundaries, we do not distribute Apple binaries. Instead, Onism Play includes a seamless 1-click import flow: download the evaluation DMG directly from developer.apple.com, drop it in, and Onism Play extracts the D3DMetal dynamic libraries into your local bottle prefix.

D3DMetal is Apple's specialized Direct3D 11/12 translator compiled directly against Apple Metal, delivering exceptional DirectX 12 performance. DXVK translates Direct3D 9, 10, and 11 to Vulkan (which runs on macOS via MoltenVK). In Onism Play's Game Tune panel, you can switch backends on a per-game basis with one click.

Yes. Onism Play integrates OptiScaler support, allowing you to inject AMD FidelityFX Super Resolution 3 (FSR 3) temporal upscaling and frame generation into supported DirectX 11 and DirectX 12 titles, dramatically improving perceived frame rates on Apple Silicon displays.

No. Onism Play is a small download (about 23 MB) with the app, store managers and bottle manager. Wine engines are downloaded and installed from inside the app in Engines & Bottles, or you can import one you built. Apple's D3DMetal is not included either; you import it from your own Apple download.

Onism Play provides first-class native integration for Steam, Epic Games, and GOG. You can sign in once, view unified library metadata, download game assets directly at maximum network speeds, and launch games seamlessly. Ubisoft Connect and the EA app each get their own bottle: install the launcher from the Stores page and play your games from it. They need an engine with D3DMetal or DXMT, because DXVK-only engines break Ubisoft's launcher. Rockstar games can't be played yet, because Onism Play doesn't support the Rockstar launcher.

Epic and GOG cloud saves sync when you play and stop, using Legendary for Epic Games and gogdl for GOG. Steam saves are handled by the Steam client itself. Onism Play can also back a game's saves up and restore them, to a folder you pick or to an optional iCloud Drive destination.

Yes. You can create a custom bottle prefix and use the 'Run Executable' or 'Install Program' feature to run any Windows .exe installer (such as DRM-free setups from GOG, itch.io, or retail discs).

Spatial audio is powered directly by Apple's PHASE (Physical Audio Spatialization Engine) and Core Audio frameworks on macOS. Connected AirPods and headphones receive dynamic head tracking and 3D acoustic room positioning. A menu-bar monitor and an in-game overlay (ctrl-cmd-A) show whether PHASE is rendering, the speaker layout and per-channel levels. Dolby Atmos bitstream output is not supported; all multichannel audio is rendered locally through Apple's spatial pipeline.

Sony DualSense, DualSense Edge and DualShock 4, Xbox Wireless Controllers, Nintendo Switch Pro Controllers, and other standard gamepads. PlayStation pads can appear to games as Xbox pads for compatibility, or as native DualSense pads per game. The Controllers page has a test sheet that shows button names for your pad, checks sticks for drift, tests vibration on each motor, and sets the DualSense light bar colour.

Zero. We do not operate analytics trackers, user profiling databases, or diagnostic daemons. No background pings leave your Mac to any Onism server. Network traffic occurs solely between your machine and the official game store CDNs you authenticate with.
