Whisky 3.9.1 lets Steam bottles follow your Mac's language and region, and fixes Game Configurations that chose a graphics backend this Mac can't run.
Changed
- Steam bottles no longer force US English. With Locale Override on Auto, Steam and the games it starts now get your Mac's language and region, so games that take their region or language from Windows (TEKKEN 8's online region, for example) see the right one. The old workaround for Steam's web helper isn't needed on current engines: Steam starts and signs in under German and Japanese on both the stable and beta engines. Launcher bottles that earlier versions set to English are put back on Auto once; Steam's own interface language is still set in Steam's settings (#340, closes #330).
Fixed
- Applying a Game Configuration no longer sets a graphics backend this Mac can't run. 27 configurations, among them Elden Ring, Cyberpunk 2077, Baldur's Gate 3 and The Witcher 3, choose D3DMetal; without the GPTK payload that left the bottle falling back to WineD3D, which can't start Direct3D 11 games. Such a backend now becomes Recommended, and the preview shows what will actually be set (#337).
- The Binding of Isaac's Game Configuration no longer switches the bottle to WineD3D. The game renders through OpenGL, which no backend setting reaches, so the change only affected the bottle's other programs. The entry now lists the black post-process effects as a known issue (#338, part of #200).
