What is the role of frame rate in 3D model optimization for games?

Frame rate is a critical performance benchmark in 3D model optimization for games, directly balancing visual detail and real-time rendering smoothness. It measures how many frames (images) the game displays per second (FPS). Optimizing 3D models—such as reducing polygon counts, simplifying textures, or using LOD (Level of Detail) techniques—aims to maintain or boost target FPS without losing visual appeal. When frame rates drop, overly complex models are often the culprit; optimizing them ensures stable, smooth gameplay, making frame rate the core driver of 3D model optimization in games.
