Game boots with illegible UI on 4k. If you log in for the first time, the game saves your character and auto-logs into that character skipping options menus entirely. If you happen to know what to click to find the options menu, you can fix the UI with a microscope. If you accidentally max the rendering slider while looking at that menu, the game will instantly crash. And because you can't log out from character select, and because you instantly crash if you go past there, and because there's no options menu at this point, you are pretty boned. We ended up having to direct the person to the website to break their autologin token.
Game should scale UI automatically with monitor sizing on first launch, and there shouldn't be a render option that infinitely suplexes your graphics card.
