Reshadeck
Reshade Shader Loader for Decky Plugin Loader for the handheld Steam Game Loader. It ships with a small curated set of shaders.
More shaders can be added at the ~/.local/share/gamescope/reshade/Shaders folder such that the .fx files are in the
root of the Shaders folder. Then you can pick and apply the shader using the plugin.
You can also designate shaders as a "screensaver" (one that blacks the screen out is included by default). Screensaver shaders start with "SS_" in their name, are enabled by pushing the aptly labeled button, and will stop running if the Deck is moved, a button is pressed, trackpad or stick activity, or the Deck is put to suspend.
Caveats
- Shaders can caused dropped frames in some rare cases and could also lead to severe performance degradation
- Shaders will not be applied at startup
- Screenshots will not contain the shader (but videos recorded via Decky Recorder will)
- When in game, the QAM menu will not have the shader applied
- When not in a game, the whole OS will have the shader applied
- You can't change any shader uniforms at run time. You have to edit the shader and change the default values
- Not all features of reshade are supported
- Some shaders can cause the Deck to crash
A note on Deck OLED Fringing Patterns
The subpixel pattern of the Steam Deck OLED (Samsung screen at least), leads to some fringing that is visible to a small minority of people. It is possible to largely eliminate this fringing using a shader. That shader is included by default in this plugin.
