kageroumado/sevoflurane: +55 stars this week

Sevoflurane

Sevoflurane brings a Proton-like experience to Mac, running Windows and macOS games from the same Steam interface. Native WebKit windows replace Steam’s Wine-rendered Chromium UI, while Steam runs in the background with macOS notifications. Older games get resizable windows and upscaling.

Highlights

Run Windows and native Mac games from one library, choosing the version per game.
Use Steam through WebKit windows while the Windows client runs in the background; receive its notifications through macOS.
Resize older games and upscale them with Lanczos, MetalFX, Anime4K, or CuNNy.
Give each game its own Dock icon and graphics settings.

Full feature list

Setup: guided Steam installation; new or existing bottles; Dormison, CrossOver, and CrossOver Preview; fonts, legacy runtimes, Rosetta, and Game Porting Toolkit installation; background setup and sevo setup.
Steam: Library, Store, Friends, chats, Big Picture, keyboard, and controller configuration in Mac windows; native menus, clipboard, launch-choice alerts, steam:// links, and macOS notifications.
Personalization: CSS styles with live reload, Streamer Mode, and Low Power Mode/Reduce Motion integration.
Compatibility: per-version ratings from Sevoflurane runs, AppleGamingWiki, and ProtonDB; anti-cheat information; library medals, native-Mac markers, and a playable-on-this-Mac filter. Linux ratings are displayed separately from the Mac filter.
Launchers: recent and installed games in the menu bar and Dock menu; Keep in Dock and a Games folder in the Dock; per-launch or persistent renderer choices; Quick Launch for external programs.
Game windows (Dormison): independent Dock icons, Game Mode, resizable fixed-resolution windows, Lanczos/MetalFX/Anime4K/CuNNy upscaling, live filters, frame-rate limits, and CPU/GPU/frame-time overlays.
Input and media: Xbox/PlayStation controller input with rumble; DLSS through MetalFX on D3DMetal. Dormison adds raw mouse input, cursor confinement, native Win32 menus, CPU caps, and hardware H.264/HEVC decoding.
Native games: macOS game installs and per-game version switching on supported engines; a game Steam for Mac already has installs from its copy without a download; optional handoff to Steam for Mac. Native NW.js games retain Steam playtime and achievements.
Game sessions: display-awake holds, stuck-game termination, complete process cleanup, Steam reconnection, and Discord activity; Dormison also relays games’ own Discord integration.
External games: Finder .exe launch and thumbnails, installer tracking, Quick Launch, non-Steam library entries, Steam Input, overlay, and run reports. Kernel-driver dependencies are reported.
HoYoverse: install, update, resume downloads, and verify Genshin Impact, Honkai: Star Rail, and Zenless Zone Zero. Optional Genshin frame-rate unlocker is off by default because it modifies game memory.
Configuration: searchable per-engine and per-game graphics, input, performance, DLL, and environment settings; known fixes with undo; dependency repair; Proton-style launch-option import.
Storage: per-game and category sizes, cache/engine cleanup, external libraries, and sharing installed games across bottles with separate saves.
Recovery: client watchdog, crash-loop detection, lost-wake recovery, orphan cleanup, helper/bottle repair, cache resets, and recovery guides. A running game survives a Sevoflurane crash; reopening reattaches.
Community: opt-in run statistics with a payload preview, per-game verdicts and notes, engine/chip comparisons, and deletion of shared data.
Diagnostics: run records, frame-time traces, logs, crash reports, per-game recording levels, redacted report sharing, Process Monitor, CPU-cap suggestions, and sevo perf compare.
Automation and updates: CLI/MCP, idle-time app updates, engine/renderer update notices, and engine switching.
