Perfectly Optimized is a Unreal Engine 5 starter template made to deliver performance gains on lower-end hardware.

Unreal Engine 5’s default configuration prioritizes ray-traced global illumination and virtualized geometry. While systems such as Nanite and Lumen work effectively on modern GPUs, they can overwhelm older GPUs and integrated graphics.

This template changes the UE5 rendering pipeline for stability and low GPU cost, delivering performance closer to Unity forward rendered games.

What This Template Is Not

• Not a gameplay framework
• Not a visual showcase
• Not a Nanite or Lumen demonstration
• Not intended for high-end or cinematic rendering

This template exists to provide a clean, fast, and predictable starting point for Unreal Engine 5 projects where performance is a primary concern.
