Ray tracing—photorealistic lighting simulating how light bounces in real world—became gaming’s next-gen graphics standard after Nvidia RTX 2000 series (2018). Control, Cyberpunk 2077, Spider-Man, Minecraft showcased reflections, global illumination, shadows at massive performance cost.
Technology
Ray tracing calculates light paths from source, bouncing off surfaces, into camera—mirrors reflect accurately, glass refracts realistically, shadows soften with distance. Previously movie CGI exclusive (Pixar), dedicated RT cores made real-time possible. 30-50% FPS hit without DLSS.
Early Adoption
Battlefield V (2018): First RTX game, reflections in puddles/windows
Metro Exodus (2019): Global illumination, eliminated baked lighting
Control (2019): Showcased reflections, indirect lighting, transparent surfaces
Minecraft RTX (2020): Transformed blocky game into photorealistic showcase
Cyberpunk 2077 (2020): Night City’s neon reflections, performance controversy
Widespread Adoption (2020-2023)
PS5/Xbox Series X added ray tracing hardware. Performance modes offered “RT Quality” (30fps) vs “RT Performance” (60fps with lower settings). AMD FSR, Nvidia DLSS/DLSS 3 upscaling made RT viable. By 2023, most AAA games included RT options.
