ESX Legacy Core — X3D Build
A faster es_extended that stops player saves going corrupt, autosaves every 10 minutes and freezes the economy before a restart. Drop-in, same resource name.
- Updated
X3D Environment
Free one-file map cleaner: no NPCs, no AI traffic, no scenarios, no idle cam, and blood, tire marks and wounds wiped away.
What to know before choosing: Optimization
The optimization category covers scripts that lighten the load on both player PCs and the server, such as map cleanup that reduces traffic and pedestrians, and a core that only saves what changed.
Always measure before and after with resmon and FXServer's profiler at peak hours. Scripts that claim to boost FPS without numbers rarely help, and a core that saves too often is a common cause of database lag in big cities.

What es_extended is, and why an ESX server should switch to ESX Legacy Core — X3D Build (free)
es_extended is the ESX Legacy core every script on the server depends on. This post covers what upstream esx_core 1.13.4 gets wrong (lost saves on crash, spawning at map origin, leaking callbacks, pre-restart dupes), what the X3D Build fixes, and how to drop it over the old one without touching a single script.
