Launching the game
Modded play is offline only. For setup, see Windows or Linux and Steam Deck.
Linux: the Steam wrapper
The launch option swofty run -- %command% starts F1 Mod Manager through Steam. It uses the configured Proton version and records session logs.
With this option set, Steam's Play button uses the manager. Clear the option to return to Steam's normal launch.
Windows
Keep Steam running, then use swofty run. The desktop Play control is still in development.
Logs
Session logs are stored in $DATA/sessions/<id>/. Use swofty logs to read the latest summary, or swofty run to follow logs during play.
In-game loader
The loader consists of version.dll and swofty_core.dll. It loads plugins and adds the MOD SETTINGS menu entry. Its log is <game>/swofty/loader.log.
The full launch and restore flow is still being connected. See Current status. Close the game and run swofty restore before returning to vanilla play.
