Bad WiFi is a real-time Minecraft Java shader effect that recreates the visual artifacts of unstable internet connections, damaged video streams, and low-bitrate compression. It solves the need for authentic digital distortion in cinematic projects, machinimas, horror maps, and stylized gameplay footage. Unlike generic glitch filters, this shader mimics specific network failure modes, making it ideal for storytellers who want to portray broken signals, corrupted frames, or limited bandwidth scenarios.

The effect is targeted at content creators, map builders, and machinima artists who require realistic transmission errors without manual post-processing. It is not designed for competitive play or everyday survival – the distortion intentionally obscures vision and disrupts immersion for normal gameplay. Honest limits: performance varies by hardware; lower-end systems may experience frame drops during heavy corruption events. The shader only works with Minecraft Java Edition and requires OptiFine or Iris.

Realistic packet loss simulation. Frames break into fragmented blocks, mimicking interrupted video transmission and unstable connections.
Macroblocking and compression artifacts. Large compression blocks, corrupted image regions, and bitrate degradation reproduce heavily compressed online video.
RGB signal corruption. Subtle chromatic offsets and color channel separation create the appearance of damaged digital signals and transmission errors.
Ghosting and frame persistence. Previous frames linger momentarily, adding motion blur from delayed data arrival.

Requirements: Minecraft Java Edition, a compatible shader loader (OptiFine or Iris), and a GPU that supports OpenGL 3.3 or higher. The shader is best used in controlled scenes – disable it for regular building or exploration to avoid visual fatigue. Some lighting mods may conflict; test in your environment before committing to a project.
