I’m still battling unpredictable load times with UEFN. On a good day the editor spins up in about a minute, roughly 30 seconds for validation and another 30 seconds for Fortnite itself (for my biggest project), but other times it just hangs or fails entirely.
My setup:
- CPU: Ryzen X9950
- GPU: ROG Strix RTX 5070 Ti
- RAM: 64 GB
- Storage: Two 14 400 MB/s NVMe SSDs (one dedicated to UEFN + Fortnite)
- Network: 123.8 Mbps down / 48.3 Mbps up (Wi‑Fi)
- In‑game performance: 400 + FPS on normal settings in Fortnite
Given this hardware, I can’t see any obvious bottleneck. After two years of UEFN development, I’m getting tired of the editor working instantly one moment and refusing to load the next. Why is UEFN so inconsistent, and how can I fix it?
