UE5 Iris Replication Optimization — Collaborative Contract

**Responsibilities**

Looking for a UE5 networking specialist to collaborate on scaling a high-population game server (The Isle: Evrima) from 200 to 300+ concurrent players. The bottleneck is Iris replication overhead — I've done extensive Ghidra RE and built the mod infrastructure, I need someone with Iris pipeline expertise to guide the optimization strategy and review implementation.

This is collaborative, not a full handoff. I implement and test, you advise on architecture and approach.

What's Needed

Filtering layer guidance — confirm whether per-connection send filtering (post-comparison) or per-actor filtering (pre-comparison) is the right approach

Dynamic NetUpdateFrequency scaling — verify Iris re-reads the value at runtime, advise on distance tiers and client-side behavior when update frequency drops

Counter system architecture — the shared CounterStruct reset array controls polling frequency. Advise on safe manipulation patterns

Review and troubleshoot — latest clean build broke MinHook hooks (dispatches=0), need to di

**Qualifications**

Deep understanding of UE5 Iris replication internals (not just config-level — the binary has stripped config classes)

Experience with runtime hooking in UE5 (MinHook, Detours, or UE4SS)

Comfortable reading Ghidra decompilation output

Familiar with: NetUpdateFrequency, PushModel, replication changelists, property comparison pipeline
