Slower computers
Laptops and computers without a graphics card.
Find these in Options, then Video Settings.
| Setting | Set it to | Why |
|---|---|---|
| Render Distance | 6 | The biggest one. Less to load means less waiting. |
| Graphics | Fast | Leaves and glass are cheaper to draw. |
| Clouds | Off | Free speed. |
| Particles | Decreased | Create machines make lots of particles. |
| Smooth Lighting | Off | The world loads faster. |
| Biome Blend | Off (or 1) | The world loads faster. |
| Entity Shadows | Off | Fewer things to draw. |
| Mipmap Levels | 0 | Saves graphics memory. |
| Always Defer Chunk Updates (in the Performance tab) | On | Keeps the game smooth while new areas load. |
| Shaders | Off | Shaders need a real graphics card. |
Memory: give the game 4 GB if your computer has 8 GB of memory, or 6 GB if it has 16 GB. Giving it more than that can make a laptop slower, not faster.
Faster computers
Gaming computers with a graphics card.
| Setting | Set it to | Why |
|---|---|---|
| Render Distance | 8 | Our server sends 8. Higher shows nothing more here. |
| Graphics | Fancy | Looks nicer and your computer can handle it. |
| Smooth Lighting | On | Softer, nicer shadows. |
| Particles | All | See every spark and puff of smoke. |
| Biome Blend | 3 to 5 | Smoother colors between biomes. |
| Shaders | Your choice | Fun to try, but turn them off if the game stutters. |
Memory: 6 to 8 GB is plenty. More than 8 does not help.
How to change the memory
Modrinth App: open the CreateBuilders instance, click the gear (Settings), then Java and memory, and move the memory slider.
Prism Launcher: right click the instance, choose Edit, thenSettings, then Java, and change Maximum memory.
Close the game before you change it. The new amount works next time you start the game.
Smoother play (optional)
Java cleans up unused memory while you play. The newer way to do that, called ZGC, does it in the background, so the game pauses less often. Our servers use it. Your game can too, by adding one line to the launcher's Java settings:
-XX:+UseZGC -XX:+ZGenerational
Modrinth App: open the CreateBuilders instance, click the gear (Settings), then Java and memory, turn on Custom Java arguments, and paste the line in.
Prism Launcher: right click the instance, choose Edit, thenSettings, then Java, tick Java arguments, and paste the line in.
It needs Java 21, which both launchers already use for this pack. If the game will not start after the change, delete the line again.
Still slow?
Close other programs, especially web browsers with lots of tabs. Plug a laptop into the charger, because many laptops slow down on battery. If it is still slow, ask in#support on our Discord.
