Adding Extra Mods Without Causing Lag Spikes

While this modpack is built for stable performance out of the box, you can expand your setup by placing extra mods into your profile's mods folder as long as you manage memory limits carefully.

Playing with Light Mods

For small gameplay, interface, or utility additions, keep your launcher set to the 6GB recommended RAM allocation. Six gigabytes is optimal for running Distant Horizons alongside anywhere from zero to 20 light mods. Avoid raising your RAM higher for small mod lists—giving Minecraft too much unused memory disrupts the Java Garbage Collector and causes sudden lag spikes.

Running Heavy Terrain Generation Mods

Massive world generation mods pair naturally with render distances of hundreds of chunks, but they require a dedicated configuration:

1. Close the game and place your terrain overhaul mod—such as JJThunder To The Max or Big Globe—into your profile's mods folder.

2. Increase your launcher's RAM allocation to 10GB. Using heavy terrain generation mods is the only situation where moving up to 10GB is recommended.

3. Create a brand-new world from the singleplayer menu so the custom terrain and distant horizons generate together without errors.

4. Pause movement briefly when first spawning in so initial chunk generation can stabilize before you travel across the landscape.
