    why don't they just create a 4th value for any given point that determines how much light it gives off (which is already in most textures...) and only render that in reflections using the existing pop in/pop out based on proximity? It's always heavy to render additional details but this seems like it would be a really light way to do it.

      Games already use a method kind of like this called cube mapped reflections. An HDRI probe (basically a sphere that's either reflective or specular) is placed in the world, reflections are rendered, and the game engine picks and chooses any given HDRI probe for reflections. There's pretty good limitations to this, such as if you want better reflections for any given area you have to add more probes and cubemaps are baked in on export, which means that you cannot take into account dynamic scenes.

      [...]

      Wow. This is exactly what Nvidia did to get real time raytracing into your hands instead of pre rendered. Or DLSS 3.5 Ray Reconstruction. What a revelation that a multi billion dollar company cannot for the life of them figure out that a random IQfyner just solved.

      Movies would look wrong if they were forced to use video game tricks for lighting.

      You can't even name a game that uses path tracing.

      Cyberpunk 2077. And it's awful, not because it looks bad or anything like that, but because it's so expensive that it reaches into impractical.

    Fixed that for you. Let me guess, you also think tessellation disappeared even though it's been used in every single game since the mid 2010s?

    theyre not but theyre fundamentally parallel machines.
    a universal function approximation makes zero sense in this context.
    ntm its gonna be way more expensive than just rendering the scene the normal way.

    when im talking about code, im talking from a point of view of craftsmanship, not checks and balances, unless i explicitly say so

    if i say an universal function approximation makes no sense in the context of rendering it has nothing to do with bottom lines, and everything to do with not having to wait seconds between your frames.

    every future graphics card and gamer system will have more and more dedicated rt hardware, the software stack is getting more complete thanks to nvidia and you get older games modded to have rt. You can expect all next gen refresh releases of older games to include RT mode on pc and future consoles.

    i fricking love hardware ray acceleration so much
    i don't think anyone under 35, who wasn't a graphicsgays, realises just how fricking amazing this shit is
    because i remember two points of view:
    1. real time ray/path tracing was always a decade away
    2. liars telling you their realtime path tracers was just around the corner (otoy brigade coming soon lol)

    it's incredible that it works as well as it does now. it's Technology with a fricking capital T. simply the most amazing tech that's been created as a result of vidya.

    within 2-3 generations it's going to mostly viable on budget cards. with 5 gens, rasterisation will be 100% dead. it's fricking amazing. keep buying xx90 cards.

    Ray tracing itself is a computationally expensive process, and does not produce good result without loads of more rays, or using tricks to bypass needing more rays to begin with. The adherence to needing over 9000 rays to get a perfect image is a foolish mindset for real time applications best left for accurate rendering by the likes of Blender and movie studios. Nobody cares if every frame out of a video game is perfectly cinema ready.

      next time when You do not know what You are talking about just do not do it alright?
      just to prove a point,
      if You had actual ray tracing,
      there would be no artifacts, ringing, smear, noise, grain, and tones of other defects,
      most importantly,
      there would not be shitty software trying to mask what You call ray-tracing as real one, it never will be that,
      but surely, for a cattle such as Yourself that does not even know a difference between illusion and a real thing, it makes none, if they put coca-cola label on milk, You would say it is coca-cola, because goyim really be like that,
      but i am pretty sure that scientifically coca-cola is more similar to milk than what You call is a real thing is to real thing

      It's not used in games.
      But it is used a lot to generate still images and movies where you can spend hours rendering just one frame.

      You can do path tracing in Blender for example.

    I'm working at a CGI company. We've been using path tracing for a decade.
    Doing it on a CPU used to take hours per frame, now with CPU acceleration it's a lot faster, as long as the scene fits into VRAM.

    The "path traced" is just the reference image.
    It probably took several minutes to generate and it's used as the ideal result all other renders should try to copy.

    They include it just to show that "ray traced" is closer to the ideal than "rasterization".
    They never implied games could look like that.
