Minecraft Java Edition Optimization Guide for Low-End PCs

March 21, 2026

Running Minecraft on an IGPU:

Running Minecraft on integrated graphics? Here's exactly what I use to squeeze 110-170 FPS out of my Intel HD 520. (tested on 1.21.11)

Step 1 : Install Fabric

All these mods run on Fabric. Download the Fabric installer from fabricmc.net, then download Fabric API from Modrinth.

Step 2 : Install these mods :

• Sodium : replaces the renderer, biggest FPS boost you'll get


• Lithium : optimizes game logic, free performance


• Ferrite Core : reduces RAM usage significantly


• ImmediatelyFast : faster GUI and entity rendering


• EntityCulling : stops rendering entities you can't see


• Dynamic FPS : reduces FPS when tabbed out, saves resources


• More Culling : extra culling optimizations on top of EntityCulling


• LetMeDespawn : improves entity performance by letting entities despawn faster


• Chunky : pre-generates chunks so you don't get lag spikes while exploring


• Note: Please check the Mods version and search if they're comapaitable with your game version.

Step 3 : InGame settings:

• Render Distance: 6 chunks


• Simulation Distance: 12 chunks


• VSync: OFF


• Max Framerate: Unlimited


• Clouds: Fast


• Particles: Decreased


• Entity Shadows: OFF


• Mipmap Levels: 0x


• Texture Filtering: None


• Chunk Updates: Deferred

Results on my Specs:

With all these mods and settings, I get between 110-170 FPS in Java Edition. That's genuinely playable and smooth for a PC with no dedicated GPU.
Without mods I was getting around 30-40 FPS , so the difference is massive.
