"From the beginning, we set ourselves the goal of delivering consistent 60 FPS gameplay across all modes of play," Holmes said. "Delivering on this goal meant re-engineering the gameplay systems at the core of our engine."Halo 5 uses a "progressive resolution system" that scales the games resolution (up to 1080p) based on what's on screen at the time. For example, large outdoor scenes with tons of vehicles and characters are more difficult to render than a few characters in a hallway."This enables us to deploy resources where they have most impact across a diverse series of experiences throughout the game while delivering the most visually stunning Halo game ever," Holmes said.
