They actually made the anti cheat compatible. You just run the exe through wine-ge (I use lutris for that) and it just works. Nothing is modified. Lutris installer also has an installer script that just runs a clean unmodified exe from mihoyo's site.
woah, so I could even just add it to steam and use vanilla proton, huh? guess it's time to make space for another couple dozen gigs in my hard drive lol
Probably works that way, because it used to be a kernel level anti cheat which Wine can't fake. If an anti cheat runs in user space (which they should, kernel level is a massive security issue), then it should run with Wine just fine.
Personally, I don't see it coming anytime soon. I played genshin on linux for maybe over a year, and with the fps unlocker for maybe almost 2 years, on both windows and linux, and have never been banned.
I stopped playing on version a few months ago though.
