The TL;DR: The game won’t launch on current steamOS, but preview build 3.7.6 fixes the launch issue.

Unfortunately the game is unable to maintain decent frame rates even with severe reductions in graphical settings.

The drastic decrease in performance compared to Doom 2016/Doom Eternal is due to the game using mandatory ray tracing for lighting.

It’s possible that we’ll see some patches or mods that improve performance, but at launch it will not be a good deck experience.

    Yes, but it’s literally limiting sales and hurting user review scores to save some predictable development hours. And the increase in performance demands means that for most users, the entire game will look worse because everything else is being penalized over a minor lighting improvement.

    Doom Eternal looks incredible and runs fantastic on deck, the ID engines have historically been famous for looking great with incredible optimization. This doesn’t live up to that legacy at all. It might have saved them some development time, but it’s literally making it a non-option for a lot of Deck users and people with weaker PCs.

      It really is a bummer that idtech of all things is moving away from working on all hardware. I played through Doom Eternal my first time on a 960 at 1080p with 60fps and never a stutter.
