Various players have been reporting a "Fatal error" being encountered when trying to play any of them. However, there's two workarounds I know of to get around it. What's interesting is that this might be specific to the Steam Deck OLED, as it's to do with HDR not working. So you can try this launch option first:

DXVK_HDR=0 %command%

To do this. Go into the game in your Steam Library, over to the little cog icon on the right for the Properties, and put that in the Launch Options box.

Another potential workaround is to force DirectX 12 for it:

%command% -dx12

You can re-enable these options by using the SteamDeck=0 %command% launch option, but this might cause the deck to crash if it runs out of RAM/VRAM.

This crash shouldn't happen if you're on SteamOS Beta (version 3.6 or newer) because it uses ZRAM, or if you've increased your swap file size. However memory having to be moved between ZRAM/swap and RAM/VRAM does cause reduced performance too, so more testing will be needed to see if it's better to use FSR3/XeSS this way or not.

The also mentioned that it will support SteamOS specifically, which I would assume means that the Deck will be specifically supported.

SteamDeckHQ has also posted a first look, and praises how well the game runs.

The game unfortunately does require a PlayStation network account.

The game has the same PlayStation overlay that's incompatible with Linux, but when playing on Steam Deck the overlay is automatically disabled. Desktop Linux players will need to use the SteamDeck=1 %command% launch option to disable the overlay.

Shadows of Doubt is amazing, but hasn't run very well on the deck. Inside areas run great, but travelling outside between buildings has had pretty severe fps drops even though the deck's hardware isn't being maxed out.

However this new experimental patch helps a lot. The deck power consumption jumps up a lot when outside, but the fps manages to mostly hold 30fps now which is a huge improvement. The recent patches have also brought a lot of controller support improvements, making it a viable way to play the game.

Fallout London requires downgrading your game version before installing the mod. The people who run Overkill.wtf (who cover handheld news and have a weekly email newsletter) made an installation script to simplify the installation.

Roblox was broken on Deck and linux by the addition of a new anti-cheat. The way the Sober app gets around the anti-cheat is by instead running the android app. This apparently has some significant performance improvements over the usual PC app as well, with people reporting up to twice the performance on the same hardware.

I know people are pretty dismissive of roblox (myself included), but it's hugely popular and it's always good to have the option.

The Jackbox Megapicker was corrupting SteamOS and forcing people to reinstall the entire OS. It's been fixed with a hot fix for now, but probably safest to avoid it until they get this all sorted out.

Name of the game is cross-post's community, playing it on our device is against ToS therefore the hoops

If you wanna know the deets, ask me in DM

if you already know, don't yell on the internet about it (like I just did lol)

The company who's handling the port is the same company that ported the previous God of War. That one ran pretty well on the deck (other than a memory leak requiring a larger swap file in some cases), so I'm hoping this one will run acceptable with the addition of FSR.

This is a developer Q&A session with Steam Deck HQ. It specifically covers a lot of questions about what was involved in getting the game running well on Steam Deck.
