The game itself works fine. I use Guild Wars 2 through Steam on the Steam Deck and then log into the launcher with my ArenaNet account.
However, the Guild Wars 2 launcher itself is insanely laggy on the Steam Deck. It's near impossible to use the mouse/trackpads. Using the touch screen works better, but inputs get registered maybe once every 20 seconds if you're lucky and sometimes doublepress or not press at all, making it a bit of a gamble to log in.
Usually it's not a huge issue since you fill in your email and password once, buuuuut since the password field is highlighted when the launcher starts, you remove your password when you accidentally press any keybind lol.
Anyway, os there any way to make the launcher not lag this badly? I googled and some people are complaining about the same problem when launching GW2 in Linux, but those posts are mostly abandoned/ years old and there are no answers and nothing about the problem specifically on the Steam Deck.
Would be nice if ArenaNet could fix this! Or if someone here knows how to fix it!
