> and even Intel admitted that ray tracing is just "brute forcing" the complex optical physics of a scene Modern ray traced games are much less "brute force" than what they were doing back in 2008. The use clever techniques and algorithms like temporal denoising and radiance caching to achieve high quality ray tracing effects with a tiny number of secondary rays per pixel (The budget is often under one ray per pixel). It's not really fair to call it "brute force" at all, just a different set of clever algorithms.
