Comparative Analysis of Energy Consumption in Unity and Unreal Game Engines

Core Concepts

Significant differences in energy consumption between Unity and Unreal Engine versions were found, highlighting potential for energy savings.

Abstract

The study evaluates the energy consumption of Unity and Unreal Engine through three scenarios: Physics, Static Meshes, and Dynamic Meshes. Results show significant differences in energy consumption: 351% in favor of Unity for Physics, 17% for Static Meshes, and 26% for Dynamic Meshes in favor of Unreal Engine. This represents a potential global saving of at least 51 TWh per year. The research aims to raise awareness about the environmental impact of video game engines.
