– FPS Booster FAQ
10 questions players actually ask, answered.
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.
Why am I still getting lag spikes when moving through chunks?
Chunk rebuild speed might be set too high, causing your GPU to work too hard at once. Lower the chunk rebuild speed setting in the config, or increase your allocated RAM if memory cleanup isn't keeping up with your modpack.
Does reducing particle effects make the game look bad?
The mod adjusts particle count dynamically based on your current frame rate, so effects stay visible while maintaining performance. You can manually set a particle limit in the settings, and the mod will scale effects down only when needed.
How does the memory cleanup work?
The mod monitors your system RAM and runs automatic cleanup routines to prevent memory leaks from building up over time. This stops sudden lag spikes that happen when your system runs out of free memory.
Will FPS Booster change how the game plays or feels?
No, the mod only removes rendering tasks that happen far away from you—gameplay mechanics, mob behavior, and world generation remain unchanged. You'll notice smoother frame rates without any difference in how the game actually works.
What should I do if mobs disappear too quickly when I look away?
Increase the mob render distance setting in the config to make mobs stay visible at greater distances. This uses more processing power but gives you more warning before mobs get close.
Can I see which settings are affecting my FPS the most?
The mod doesn't include a built-in profiler, but you can test by adjusting one setting at a time (like chunk rebuild speed or particle limit) and checking your frame rate to see which has the biggest impact on your system.
