Surprise! Live++ hot-reload running on SteamDeck Proton. This is a debug build with the SteamDeck connected over Wifi. Final performance will be <1s reloads.

So. Remember when Valve announced a VR headset that also plays Windows games? Remember when I played a Windows copy of Silksong on my Android phone? Valve planted the seeds for *all* of that. It's the same technology. Valve is behind Fex. www.theverge.com/report/82065...

Steam Machine today, Steam Phones tomorrow

The Steam Frame is a Trojan horse carrying Arm’s gaming future.

SteamOS 3.7.6 Preview now out with a launch failure fix for DOOM: The Dark Ages.

Fix coming.

Timo Schmidt@timo.deckver.se · last yr.

JFY: DOOM The Dark Ages doesn’t launch on the Steam Deck and crashes during the intro. Unfortunately, I haven’t found any workaround so far. Unless @plagman.bsky.social and team are working on a fix, TDA won’t be playable on the Deck for now.
