Laughless Saint Steam Deck Compatibility

The current rating: none

Checked on 24 August 2026, Valve’s Deck compatibility report for app 3849000 returns no resolved category — the game has not been tested and rated.

That is worth stating precisely, because “unrated” is often misread as “does not work”:

So nobody has told you it does not work. Nobody has told you it does, either.

What we can reason about from the specs

The game does not ship a Linux build — Steam lists Linux support as false — so on a Deck it would run through Proton.

The minimum requirements are the useful data point:

A GTX 970 floor is meaningful. That is above what a Deck’s APU comfortably matches at native resolution, which means anyone hoping for a smooth Deck experience should expect to be turning settings down rather than up. See system requirements for the full list.

We are not going to publish a frame rate estimate. We have not run the game on a Deck, and inventing benchmark figures would be exactly the kind of thing this site exists not to do.

Settings that would matter most on a Deck

If you do try it, the developers have shipped options during early access that map well onto handheld constraints:

• Turn off shadows — Update 7 added this explicitly “for significantly improved performance”
• Saturation slider — Update 7, useful on a different panel
• UI symbols for smaller screens — Update 7 replaced certain UI aspects with symbols for smaller screens, which is directly relevant to a 7-inch display
• Skip intro — Update 7, small but welcome on repeat launches

There is also a known VRAM issue that is worth flagging for any memory-constrained device: Update 6 included an “attempt at fix for texture streaming issues for GPUs with 4 or 6 GB of VRAM,” and Hotfix 5 fixed a VRAM leak that caused degraded textures. Both suggest memory pressure has been a real problem on lower-end hardware.

Controller support is only partial

Steam lists Partial Controller Support, which on a Deck means some interactions expect keyboard or mouse. The Deck’s trackpads and virtual keyboard cover that, but it will not be a seamless pad-only experience. Controller rolling and quantity selection were both improved in Update 6, so this is an area under active work.
