@Cubuss Again this is purely to do with steam decks. Not linux in general. Had there been no steam deck there would of been no update at all for that. But, because steam deck at the time could only run Linux its what was used due to that. You will not find 1 single shred of evidence online supporting EA or Respawn openly stating they support linux.
What you will find in apexs 5 years of existence is 1 single trello post that specifically states steam deck and people are reaching for stars because it has the word linux in it. Ignoring the main factor Steam Deck. lol
