Citra Shader

Choose between OpenGL, Vulkan, or software renderers based on your system capabilities.

For users wanting advanced post-processing capabilities, ReShade integration offers a powerful alternative. ReShade is a generic post-processing injector that works with many games and emulators, including Citra.

The first time a new scene, effect, or character appears, Citra compiles a shader, causing a momentary frame drop or "stutter."

Clearing or updating your shader cache can solve graphical glitches where textures turn black or models don't render properly. How to Manage Citra Shader Cache (Fixing Stutter)

Turn this ON. It ensures that any uncompiled shaders will not pause your game loop while loading. Enhancing Visuals with ReShade and Custom Shaders The first time a new scene, effect, or

It's important to distinguish between the shaders used internally by Citra to run a game and the external custom shaders you can add for post-processing effects.

vec3 result = color; if (subpixelIndex == 0) result.g *= (1.0 - intensity * 0.5); result.b *= (1.0 - intensity * 0.5); else if (subpixelIndex == 1) result.r *= (1.0 - intensity * 0.5); result.b *= (1.0 - intensity * 0.5); else result.r *= (1.0 - intensity * 0.5); result.g *= (1.0 - intensity * 0.5);

Originally, Citra translated these shaders in real-time. When you entered a new room or a Pokémon used an attack for the first time, your game would freeze or drop frames while your hardware compiled the code. The Solution: Disk Shader Caching
