List of first-person shooter engines

This is a sortable list of first-person shooter engines. == Early 1970s - Late 1980s: wireframes to flat-shaded 3D == == Early 1990s: 2.5D environments, sprites, and textures == == Mid 1990s: True 3D Environments, texture mapping/polygons, sprites-to-per-vertex animation transition, beginnings of 3D Graphics hardware acceleration (3dfx glide-NVIDIA) == == Late 1990s: 32-bit color, per-vertex-animation-to-skeletal animation transition == == Early 2000s: First GPU (GeForce 256)-GPUs become standard, Increasing detail, Hardware T&L, outdoor environments, skeletal animation-standard, baked/dynamic lighting, ragdoll physics == == Mid 2000s: High-Dynamic Range (HDR) lighting, multi-threaded physics, programmable 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.
