Frequently asked questions

How do I start using FPS Booster after installing it?
The mod works automatically once installed—no setup required. Open your settings menu in-game to find the FPS Booster config panel, where you can adjust render distance for mobs, particle limits, and chunk loading speed to match your hardware.
Will this mod work on multiplayer servers?
Yes, FPS Booster is fully compatible with multiplayer servers and won't cause desync or affect other players' experience. The mod only changes what your client renders, not the server's game logic.
Can I use FPS Booster with other mods?
Yes, it's designed to work alongside large modpacks without conflicts. If you experience issues with specific mods, try lowering the chunk rebuild speed or particle limit settings to reduce competition for system resources.
What's the difference between mob render distance and block render distance?
Mob render distance controls when distant mobs and their animations stop being drawn, while block render distance affects when heavy blocks like chests, banners, and signs stop rendering. You can adjust these separately based on what causes the most lag for you.
