So many different guides / tutorials online, but sadly every one I try comes up short in some way.
I really don’t want to have to dual boot Windows.
Kinda hoping there’s an HNer that figured out.
Thanks.
But Steam -> custom app -> battle.net exe -> run it in 'compatibility/proton mode' and you should be good.
I'm on vanilla Ubuntu 22.04 but have also tried vanilla 24.04, with an Nvidia card.
That said, I thought steamdeck was just the handheld device - not sure if this would help with my Ubuntu situation - but I don't know enough about steamdeck so perhaps I am misinterpreting your comment.
Thanks either way.
ProtonDB is a site that aggregates reports from users of Proton, the compatibility layer to let Windows games run on Linux. For lots of games, users will submit reports of their system info (distro, CPU, GPU, driver version, Proton version) and any configuration they needed to do to get that game working on their setup. The usual solutions are switching the Proton version you use and/or commands you add to the custom commands in the configuration for that particular game in the Steam menu.
I just looked at Diablo 4, and specifically filtered for Ubuntu users; I see 22 reports, with the most recent ones being people saying it worked for them. There are also successful reports from people on Linux Mint, which is based on Ubuntu.
Albion Online is another one with great great portability, literally on everything.
Instead, I'd recommend switching to something more optimised for gaming, like Bazzite or Nobara. Both work fine with nVidia cards.
But I also recommend trying a different Proton, like Proton Experimental or Proton-GE, as they often get compatibility updates before mainstream Proton.
