OptiFine HD — Configuration

Configuration & Video Settings

OptiFine expands the standard Video Settings menu with several sub-menus for deep customization.

Quality Settings

• Mipmap Levels: Adjusts the smoothness of distant textures.
• Anisotropic Filtering: Sharpens textures at an angle.
• Antialiasing: Smooths jagged edges.
• Emissive Textures: Allows parts of a texture to glow in the dark.
• Custom Fonts/Colors/Sky: Toggles for various resource pack features.

Performance Settings

• Smooth FPS: Stabilizes frame rate by flushing the graphics driver buffers.
• Fast Render: Optimized rendering algorithm that can significantly boost FPS.
• Lazy Chunk Loading: Spreads out chunk loading over multiple ticks to reduce lag.
• Smart Animations: Only animates textures that are currently visible on screen.

Details & Animations

• Clouds: Toggle between Fast, Fancy, or Off.
• Trees: Control leaf transparency.
• Animations: Individual toggles for Water, Fire, Redstone, Flames, Smoke, and more. Disabling these can provide a major performance boost on low-end systems.
