This is a sortable list of first-person shooter engines.
Early 1970s - Late 1980s: wireframes to flat-shaded 3D
Early 1990s: 2.5D environments and textures
Mid 1990s: 3D texture mapping , beginnings of hardware acceleration
Late 1990s: 32-bit color, GPUs become standard
Early 2000s: increasing detail, outdoor environments, ragdoll physics
Mid 2000s: dynamic lighting, early shader implementation
Late 2000s to 2010s: high-resolution textures, widescreen resolution, unified shader model
2020s: 8K, real-time ray-tracing
Specialized engines/engine middle-ware
Some features may be integrated into engines. For instance for trees and foliage a special "engine" is available, SpeedTree, that does just that (or could be integrated into general engines). The Euphoria character's 3D animating engine can be used independently but is integrated in the Rockstar Advanced Game Engine and the game Grand Theft Auto IV.
