    I was impressed with it in alan wake 2 since not only did it have better performance than the denoisers but it also made lower upscaling qualities look more bearable ( mostly better preserved detail)

      every instance of ray reconstruction has made the image look like an oversharpened oil painting in motion, i absolutely hated it. all these games with blurry ass taa and dlss, dont need ray reconstruction to make it 3x worse, even with the small performance and visual enhancements otherwise.

    Ray Reconstruction looks brilliant but I agree with the closing statements. RR seems to make some reflections (at least in my Cyberpunk Phantom Liberty playthrough) sharper or cleaner than they should be.

    I wanna crawl under Jensens desk for greenlighting RTX Remix as an entire tool rather than just a demo to show off why "you should care about RT". The only issues is that right now its limited to older APIs exclusively and therefore heavily minimizing the potential games to be "remixed". I sincerely hope they find a way to open it up to more modern DirectX versions

    Alan Wake 2 has the same problem that Cyberpunk has. Ray reconstruction is great for geometry but it makes faces look weird if they are not up close to the POV.

  • @1chrisanderson

    At its core, i think RR will always show some degree of sharpening or edge enhancement. Correct me if i'm wrong, but i liken it (in my own mind) to running a set of photoshop actions on a super noisy photo. Gaussian blur followed by a few rounds of clarity boosting, unsharp mask, contrast enhancement etc. I know it's 'using AI' to do more nuanced things but it's always seemed kinda vague as to how it enhances things like reflections more than character faces. As far as why it integrates better into Alan Wake PT, i think the more painterly/softer art style allows for the RR clarity boost without being obvious and i'm sure Remedy tuned it to some degree. I would imagine there are config values that let you customize its behavior when implement it into a project but i'm not a dev.

    • @Coollok100
      @Coollok100 29 днів тому +4

      It's definitely true that RR (and other upscaling techniques) will always have some level of artefacts, but these won't necessarily resemble sharpening/edge enhancement. At its core what these models are attempting to do is make a prediction of ground truth from a limited set of data - they could equally as well over-smoothen rather than over sharpen.
      Better models should be able to get closer to the ground truth, but within a level of model quality you might see some tuned to over predict edges and detail vs some that over smoothen them (and there's probably an element of postprocessing in there too) - it's more of a design choice than a limitation on the process itself

    • @gameguy301
      @gameguy301 27 днів тому

      you are thinking of it like photo editing where you are trying to solve noise with screen treatment of a single existing image, but RR like DLSS is more about selecting the representative data from the bucket of samples that where accumulated temporally. that means you arent just treating the current image, you are looking back at the previous 4 or 8 images and trying to reconcile what information from them is still relevant and re-usable.
      RR improves quality in 2 ways.
      1. the ML approach should just be better at the task than regular denoisers unless they were meticulously hand tuned on a per game, per effect basis.
      2. you are no longer doubling up on temporal accumulation as you are no longer feeding a temporally denoised image into DLSS to be temporally upscaled, DLSS + RR does both denoising and upscaling in a single step so you don't compound your sample re-use.

      @brainycabde 29 днів тому +2

      Yeah, Quake had good results because of the fact that most of the image is 3D whereas Duke 3D is uses a lot of sprites. Could probably still be done, especially if someone remakes the assets in 3D.

      For Deus Ex, modders had to make a new renderer (the Echelon Renderer) to make it work with RTX Remix. Maybe something like that is at play in Duke 3D as well.
