Here is a Reddit forum about it so you can see it’s not just me i tried the launch steam=O and the ** you mentioned as well as proton and adding a seperate Sd card i installed it to so the launch would possibly not be effected by the fact that the game thinks it’s a steam deck making a small window and locking you at 800p nothing works.

This guy was saying he was able to fix it by changing the code but that’s something I’m not really capable of however here’s what he did if this helps you on your end. [Feature Request] SteamOS Automatic hardware detection · Issue #2585 · ValveSoftware/SteamOS · GitHub
I tried the steamdeck=0 %command% at launch still locked in 800p on steam machine also tried toggling on and off the recognize as a steam deck option. Strangely i was able to get high resolution afterwards on the crucible legacy edition however the current public edition which of course is where my characters are did not work. I hope we can get this fixed soon with a hotfix update as I’m dying to play it on my tv that’s the reason i bought the steam machine in the first place.
Thanks for your attention to this matter.
