--- Comment #4 from Anastasius Focht focht@gmx.net --- Hello,
--- quote --- Because I'm using Steam and some new games launch only in "Windows 7" mode. --- quote ---
sharing multiple Steam games in the same WINEPREFIX, each requiring different settings (Windows versions, VC++ runtimes, DX versions/overrides, .NET runtimes), can be a recipe for disaster. At one point you will have the prefix messed up beyond repair.
Do that at your on risk but be aware bug reports coming from such configurations will be automatically flagged 'invalid' (waste of time to analyse/dissect problems resulting from such prefixes).
Regards
