Are you looking to increase FPS in Minecraft 1.21.4 and remove lag? If so, this guide is perfect for you! Optifine is one of the best tools for improving Minecraft performance, and with the right settings, you can significantly boost FPS, even on low-end PCs.
In this tutorial, I’ll show you the best Optifine settings for Minecraft 1.21.4 that will help you achieve smoother gameplay, better performance, and no lag!
What is Optifine?
Optifine is a powerful optimization mod for Minecraft that enhances performance and improves graphics. It allows the game to run faster and look better, with added features like dynamic lighting, HD textures, and shader support.
Why Should You Use Optifine?
- Increases FPS (even on low-end PCs)
- Supports HD textures and shaders
- Gives more control over graphics settings
- Allows dynamic lighting and better animations
- Helps reduce lag and stuttering
Alternative Mod: If you’re on a very low-end PC, you might want to try Sodium, a performance mod that boosts FPS even more. However, Sodium doesn’t support shaders, so Optifine is the best choice if you want better graphics.
