What ReShade is
ReShade injects post-processing shaders into a graphics pipeline. It operates after the engine renders the frame — adding tone mapping, sharpening, color correction or grain.
Setup checklist
- Download ReShade from its official site.
- Point the installer at your Dusk install folder.
- Choose the rendering API Dusk uses (Vulkan typically).
- Pick or import a preset — start light.
- Toggle the overlay in-game with the configured hotkey.
Reasonable presets
- Sharpening: subtle (CAS at ~30%).
- Vibrance: minor lift; avoid oversaturation.
- Vignette: very gentle if at all.
- Film grain: optional; keep low.
When to disable
- FPS drop is noticeable beyond a single shader effect.
- Specific scenes break or look wrong.
- Anti-cheat systems flag the injected library (n/a for Dusk in single-player).
