Frequently asked questions

Where do I find the performance mode button?
Open Options from the pause menu, then click Video Settings. The Mode button is in the top-right corner of the video settings screen. Click it to cycle between Super Fast, Balanced, and Vanilla modes.
What's the difference between Super Fast and Balanced mode?
Super Fast uses vertical culling to stop loading caves and blocks beneath you, giving maximum performance for older computers. Balanced mode uses smart entity culling to skip processing distant mobs and items, offering a middle ground between speed and visibility.
Why am I getting random freezes even with this mod?
The Auto-RAM Cleaner runs every five minutes to clear unused memory. If freezes still happen, try switching to Super Fast mode or closing other programs running in the background.
Can I see particles like rain and explosions with this mod?
Yes, the Particle Optimization feature keeps rain, explosions, and redstone dust visible while changing how they load to prevent lag spikes. Far particles beyond your view distance are removed to save performance.
