UE5 Peformance Regression After Hardwae Upgrade

Hi everyone,

I’m experiencing a strange performance regression after upgrading my PC. I am working on a scene in UE5.6 featuring dense foliage.

On my old build, the project ran smoothly. However, on my new build, I’m seeing significant frame(pld 40fps → new 15fps ) drops and the Input latency (measured via Stat Unit) spikes to 200–300ms during play.

Specs Comparison:

Old PC: AMD Ryzen 7 3700X | RTX 3060 (12GB) — Smooth performance.

New PC: AMD Ryzen 7 7700 | RTX 5060 Ti (16GB) — High input lag & stuttering.
