About this project
What does tickfix add?
TickFix
Advanced gameplay optimization mod that improves Minecraft's tick processing by intelligently managing background calculations and reducing unnecessary workload during gameplay.
TickFix focuses on optimizing the internal tick system by deferring non-essential calculations when they are not immediately required. This helps reduce CPU usage, improve server and client responsiveness, and create a more consistent gameplay experience with fewer performance spikes.
Designed to work silently in the background, TickFix maintains vanilla behavior while making tick updates more efficient, especially in situations with heavy world activity, large builds, complex farms, or high entity counts.
