Games Can Cut Power Without Looking Worse

Video games can cut electricity use without always looking worse. Microsoft’s Halo Infinite energy-efficiency case study says the team reduced the resolution of a blurred pause-menu background to 1080p and measured about a 15% reduction in power use, with total AC power falling to roughly 165 watts in that test state. Microsoft says the change did not negatively affect the player experience.

Digital Foundry tests PS5’s Power Saver mode and measures how supported games trade some performance headroom for substantially lower power draw.

Sony now offers a player-facing version of the same idea. Its PS5 power-saving guide says supported games can scale performance back when Power Saver is enabled. Sony notes that some features, including VR mode, may be unavailable while the setting is active.

Players have long noticed that different games and rendering modes can produce different console power draw, even on the same hardware.

The larger lesson is that gaming energy use is partly software-defined. Menu rendering, frame-rate targets, resolution, idle behavior and unnecessary background work all affect how hard the CPU and GPU must run. That makes energy efficiency another optimization target alongside technologies such as faster shader delivery, AI upscaling and new game-development tooling.
