I and my brother are playing Skyrim from the same computer (using Family Sharing). The problem is that I prefer to play in English but he needs a localized version. There is the localized version in Steam, but each time I switch languages in Steam Skyrim settings, it downloads 3.5 GB of language files. It takes some time to download so have to wait each time before a game, and also I'm a bit worried about my SSD - it's additional 7 GB of writes each day.
So is there a way to not download it each time? I tried to save language files and replace them when needed, but Steam starts download anyway. And I have not found an option to disable auto-update. Maybe it's possible somehow to have 2 different installations of Skyrim from Steam on the same computer? Or have English voice with localized subtitles? That variant would suit us both.
