PSX Shader recreates the jittery vertex wobble, affine texture warping and dithered look of original PlayStation graphics — a nostalgic, low-cost novelty that turns any world into a 90s throwback.

How to install PSX Shader

1. 1Install a shader loader for Minecraft 1.20 – 1.21 — Iris (pairs with Sodium) or OptiFine. PSX Shader is a shaderpack, so it needs a loader to run.
2. 2Download the PSX Shader .zip from the button above — keep it zipped. It is mirrored on MineSpecs, so there is no ad-gate or redirect.
3. 3Drop the .zip into your .minecraft/shaderpacks folder (%appdata%\.minecraft\shaderpacks on Windows, ~/Library/Application Support/minecraft/shaderpacks on macOS).
4. 4Launch the game, open Options → Video Settings → Shaders, and select PSX Shader.

Performance & what to expect

PSX Shader is rated potato performance impact. It is the lightest tier in the catalogue — it runs on integrated graphics and older laptops. The look is cartoon and cursed.
