Citra Shader |top| Jun 2026

To understand Citra’s shader implementation, you must understand the original hardware:

void main() vec2 uv = gl_FragCoord.xy / tex_size; vec4 color = texture(color_texture, uv); citra shader

These shaders are small pieces of code that alter the visual output of the emulator. They are used to simulate the look of old CRT televisions, smooth out pixelated graphics, or apply artistic effects. xBRZ and 5xBR If you miss the physical

: Great for smoothing out jagged edges on text and sprites without a huge performance hit. xBRZ and 5xBR To understand Citra’s shader implementation

If you miss the physical look of the 3DS screen, LCD shaders can simulate the sub-pixel grid, making the emulation feel less like a "PC port" and more like the original hardware. Popular Shaders to Try

Here is a detailed write-up on the technical aspects, usage, and popular types of shaders in Citra.
