Open the “Shaders” menu in video settings. Select a shader pack from the list. Wait for the game to apply the shader. Adjust shader options for better performance if needed.

Recommended shader packs

Choose lightweight shaders for low-end systems. Use balanced shaders for stable performance and visuals. High-end systems can run advanced shaders with full effects. Always test performance after enabling a new shader.
