Infinite Geometry in Your Pocket

The promise of UE5 was “limitless polygons.” The promise of UE6 is “limitless platforms.” Previously, Nanite (virtualized geometry) required high-end desktop GPUs. Epic has optimized the cluster culling algorithm to work on ARM-based chips found in the Snapdragon 8 Gen 5.

Project: “Citadel”

The tech demo, running on a Galaxy S26 Ultra, displayed a medieval city with 8 billion triangles. No pop-in. No LODs.

“We realized that the bottleneck wasn’t the GPU, it was the memory bandwidth. By compressing the mesh data using AI upscaling at the vertex level, we reduced VRAM usage by 60%.”

What this means for Indie Devs

You no longer need to optimize assets for mobile separate from PC. Build once at maximum fidelity. The engine automatically scales the virtualization logic based on the target device’s NPU capabilities.
