Ray Tracing ne anlama geliyor?

Yeah, ray tracing is basically what separates "looks like a 3D model" from "catches your breath". At its core, it’s a brute-force simulation of how light physically behaves: you shoot rays from the camera through each pixel, bounce them off surfaces, calculate reflections, refractions, shadows, and even global illumination—then do it again for every possible interaction until you get close to realism. Real-time ray tracing is where it gets brutal. Current GPUs cheat by approximating paths, using denoising algorithms, and relying on hybrid rendering (rasterization + ray tracing). It’s still wildly expensive—even the RTX 4090 struggles to hit 60fps at 4K with full path tracing in Cyberpunk 2077, and we’re a long way from open-world games running it natively. The trade-off now is quality vs. performance: do you halve your FPS for cinematic-grade reflections, or bake lighting and fake it? In film, ray tracing (or rather, full path tracing with Monte Carlo integration) has been the gold standard for over a decade—just look at Pixar or Marvel CGI. Movies don’t care about FPS; they render frame-by-frame for hours per image. That’s why we got so spoiled: every specular highlight, subsurface scatter, and ambient occlusion looks *real*, not like plastic. In games, it’s a luxury—until DLSS and FSR get good enough (or until hardware catches up), ray tracing will remain a toggle. But once it’s seamless? That’s when games start looking like cinematic experiences, not animated sprites in 3D.
