AntifreeZe
Up to +400% FPS in heavy zombie load scenarios!
AntifreeZe is a pure server-side DayZ mod designed to improve server performance and reduce CPU load when zombies cannot reach the player behind walls, windows, or on elevated positions.
Real benchmarks show 4–6x performance gain in scenes with hundreds of active infected.
Ideal for high-pop servers, PvE events, or large-scale horde gameplay.
How it works
- Optimizes infected AI logic (ZombieBase).
- Freezes unreachable zombies to stop useless pathfinding.
- Culls extra AI in dense local clusters.
- Keeps nearby zombies fully vanilla and responsive.
- No client installation required — server-side only.
Performance and optimization
AntifreeZe significantly reduces CPU usage and stabilizes FPS under heavy AI load.
Useful for:
- Massive PvE events.
- Crowded towns and player hubs.
- Horde-style or infected-rich zones.
- Servers with increased AI spawn counts.
The mod intelligently pauses AI that cannot reach players, avoiding wasted CPU cycles and preventing server frame drops.
Experimental notice
Developed as part of issue T195642[feedback.bistudio.com].
This is an experimental optimization layer — it may change the default zombie behavior, but provides a real and measurable performance boost.
It does not modify damage, loot, or spawn systems.
