I’m on PC and I haven’t noticed anything changed. Literally. I don’t notice any bugs nor have I noticed a sudden improvement of my graphics. It seems to me that the 15gb that Steam downloaded, was just full of 0’s and don’t do anything.
Edit: Nevermind, apparently the new quests and items are part of the update, so in that case I have definitely noticed something lol.
Besides that, in my experience movies with foreign languages usually have the subtitles embedded in the file itself (usually as ASS / SSA format), so maybe try to download movies with embedded subtitles.
