Video game graphics have evolved rapidly, but nothing transforms a game quite like global illumination.Ray Traced Global Illumination (RTGI) changes how light bounces off surfaces, creating realistic shadows and lifelike reflections.While official path tracing usually requires an expensive RTX graphics card, you can achieve a similar next-gen look on almost any GPU using ReShade.

Most RTGI shaders are post-processing approximations, not true hardware-accelerated ray tracing (NVIDIA RTX/AMD RDNA). They rely on:
