SUWSF VS hephaistos

Not sure about the second question, but I think the ultrawide resolution for half screen (when unsupported by the game) uses SUWSF which is a tool injected like Reshade. The game handler takes care of the configuration and loading, might wanna check if there's anything preventing it hooking the process, like Discord overlay or MSI afterburner.

There were definitely a lot of things of fix, this mod was more involved than the typical ultrawide fix mod. I don't say this to brag, but it is the case that the vast majority of UW fixes are for 3D games where one only needs to remove intentional limitations on viewport / aspect ratio with a hex patch and it's done (example: Horizon Zero Dawn), hence why generic solutions such as SUWSF are very useful. For Hades there was a tremendous of additional custom work required so that UI elements are properly positioned after resizing the viewport.

You can also use SUWSF (download the x64 version and extract it so that dsound.dll is alongside the saints row exe and then rename dsound.dll to version.dll) so that you don't have to figure out the correct bytes for your specific resolution.

-SUWSF (no change)

I have pushed 2.0.1 to fix this, thank you for your report! I don't know how that slipped by me https://github.com/PhantomGamers/SUWSF/releases/tag/2.0.1

I made a new version of SUWSF that has the change to the thread locale which might fix the issue, but if not I also added logging to disk which should tell us where it is failing. The version is available here: https://github.com/PhantomGamers/SUWSF/releases/latest (download SUWSF.zip)

Quick tip, you can install this in Desktop mode (it's an easy process) to make Hades fill the entire Steam Deck screen (without black bars on top and bottom). It looks even better that way.

You can run it in 16:10 using this https://github.com/nbusseneau/hephaistos

With this small mod from github

The game is locked in 16/9 aspect ratio though, I recommend you use Hephaistos if you’d like to run it without black bars on the computer’s internal display :)

Hephaistos mod author here. The issue happens because your monitor reports back too many supported resolution to the game, and the list of resolutions available gets trimmed to 9.

The game doesnt properly support the deck's resolution so it's letterboxed, but there is a mod to change that if it bothers you: https://github.com/nbusseneau/hephaistos
