Damn, that’s a shame. I had the same issue with lutris so i thought for sure it’d be the same solution. I’d probably give up for a bit too. There’s a handful of things I want to do but I started to get burned out on issues so I’ve been putting them off.

Forget Lutris, just use heroic game launcher. Click Add game, select the battle net installer exe, run it and let it install, close it then switch the path to the installed battle net exe. Heroic will use proton ge (i believe by default) and it’s worked for me without issue. I tried lutris first because that’s what showed up online when I searched and I had nothing but issues. Then I did it in steam, with similar steps to what I described already and I could get it to work, but in heroic it was just a couple minutes and it’s good to go.

Not only that, but the steam deck exists, the gabecube is coming, Linux gaming has been on the rise. The shit you did “several years ago” is irrelevant. If they allowed Proton, windows players with steam decks can now also play on the go. Instead they repeatedly have to poorly explain why they won’t… to stop basically 0 cheaters. I’d be willing to bet that the only people who actually stopped cheating in rust when Linux support was dropped did so because they lost interest anyway.

I searched just to see, there’s a python script right on github that claims to have an aimbot, esp, wallhack, no recoil and several other features, along with “safety settings” so you don’t get caught. Does it work? I don’t know, but the codes right there to look at and there are dozens of other results in the search.
