hephaistos VS decky-loader

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

The repo has instructions for Linux/Steam Deck: https://github.com/nbusseneau/hephaistos

If you haven't installed Decky Loader, you can do that by following the instructions at https://github.com/SteamDeckHomebrew/decky-loader

Here is what happened: I did some Desktop mode stuff recommended by a friend. In essence I succesfully installed the Decky Loader and afterwards installed the PowerTools as described here: https://github.com/SteamDeckHomebrew/decky-loader

Decky Loader and it's plugin vibrantDeck. Set saturation to 200% to achieve somewhat-OLED-like colors in game. Alternatively, someone said that ReShade also does the job (see the same optimization guide here).
