Best Optifine Settings for FPS Boost

After installing Optifine, just pick Optifine from the drop-down version menu in your launcher and run it. After opening the game, head over to the options and then video settings to apply the best Optifine settings for FPS.

Graphics (Fast recommended):

• Fabulous: Increases quality of translucent blocks, lowering FPS and making it the slowest option.
• Fancy: Increases the quality of the game, decreasing FPS.
• Fast: Lowers the overall quality of the game but increases performance and FPS.

Smooth Lighting (OFF recommended):

• OFF: No smoothing, making the game faster.
• Minimum: Simple lighting, balancing both quality and FPS.
• Maximum: Most complex lighting, making the overall game slower.

Smooth Lighting Level (OFF recommended)

GUI Scale (1 recommended):

• Keep it as small as you can. Smaller sizes are considered the fastest. Values above 3 are only available for 4K displays.

Dynamic Lighting (OFF recommended):

• OFF: No dynamic lighting.
• Fast: Dynamic lighting with 500ms latency.
• Fancy: Real-time dynamic lighting with 0ms latency.

Shaders (OFF recommended):

Just turn your shaders off. Minecraft shaders are the most resource-intensive, so disable them for more FPS. Enabling shaders can conflict with other Optifine settings for FPS boost, making your game laggy.

Render Distance (2-6 recommended):

Keep render distance as small as you can. If you’re using an old PC and struggling with FPS, drag it to the lowest setting (2). This will make your game look ugly but will surely increase your FPS.

Max Framerate (Max/Vsync recommended):

Keep it at max or Vsync. Enabling Vsync will limit your FPS to the refresh rate of your monitor. Keeping it at max is the same thing, though it will increase FPS; extra FPS above the refresh rate won’t be visible.

View Bobbing:

Enables bobbing of the character while walking. It does not affect performance.

Entity Shadows: Optional (You can keep it on or off according to your preference)

Attack Indicator: Optional

Dynamic FOV: Adds an extra field of view while running or flying. It does not affect FPS.
