Why Lumen Lighting System matters

Dynamic lighting supports the visibility and atmosphere of multi-layered skies. It is a rendering feature, not an announced weapon or aircraft-upgrade mechanic.

What is confirmed—and what is not

The final graphics menu, hardware-ray-tracing relationship, quality presets and console implementation have not been fully shown.

Practical player guidance

Do not use the Lumen name alone to predict performance; rely on the published minimum target and later measured benchmarks.
