■Summary
This presentation examines the environmental impact of video games, highlighting the challenges of integrating green computing practices into development workflows. It introduces the Game Performance and Energy Efficiency Quadrant (GPEEQ)—a framework for evaluating the trade-offs between frame rate and energy consumption, using two metrics: Power up and Frame up. Alongside this framework, the presentation proposes a hardware-specific optimization approach that applies evolutionary algorithms to reduce energy use by tailoring ad-hoc sequences of LLVM code transformations. A case study on Doom Legacy, running on a Raspberry Pi 4, demonstrates the approach’s potential, achieving up to 26 times lower energy consumption than standard -O3 optimizations. Together, these tools advocate for a shift toward sustainable game development practices that balance performance with environmental impact.
