I’ll add I installed it on my OLED deck, and no obvious issues stand out. Chucked nix on it with the Determinate Nix Installer and deployed my Pipewire EQ and vkBasalt configs without issue (and without some of the audio output issues that SteamOS introduced with the 3.5 update). Oh and vkBasalt comes installed OOTB, which solves some maintenance annoyances with keeping it working on SteamOS.
Steam game mode UI feels slightly snappier, perhaps down to using the BORE CPU scheduler (but it could be placebo of course).
