Works perfectly out of the box

You can Max the Graphical Settings out, and still get a 60 out of it, which is impressive enough. Though it drains the battery a little too quick, even on OLED. You can still get a few hours out of it, though expect having to recharge your Deck as soon as you're done with one episode.

Keyboard inputs sometimes get nullified when pressing multiple keys.

I'll will try to tinker and make it work but as for now with a vanilla steam deck it isn't a great experience on the Steam Deck
large freezes
I was losing the largest part of audio tracks and I had terrible stutters that would last up to 5 seconds
No issues or slowdowns noticed in Episode 1.
Works Perfectly.
Seems playable based on the short time I tried it. Have some hiccups like other people here mention, mostly during new scenes.
Works out of the box
short freezes through loading times

Changed the launch options for the game and made it as "PROTON_NO_ESYNC=1 PROTON_USE_WINED3D=1 %command%"
The game had no lightning at all and a lot of things were glitchy, from items like a telephone turning into a big corrupted mess or the whole office being dark or Sam and max are glowing basically a lot of problems
When I went to windowed and then full screen It's sort of a different resolution instead of my default one so it doesn't fill the whole screen even when changing resolutions
The mouse was slower than it was on other games and on the desktop
In the intro the car was flipping like a dolphin for some reason
