In this example, the magical element is the fire being caused by the intensity of a womans passion, which is not a realistic cause-and-effect relationship. It's doing so with Frame Generation, and based on the efficacy of Ray Reconstruction so far, I'd say AMD would do well to find a way to ape this one, too. Magical realism often involves fantastical or magical elements that are presented in a matter-of-fact way and are seamlessly integrated into the storys setting and characters. Sure, the effect can still be subtle, but why wouldn't you?Īt this point AMD must be cursing Nvidia for consistently coming up with new, effective graphics features that it has to then go ahead and figure out a way to copy. Field of Dreams (1989) PG 107 min Drama, Family, Fantasy 7. The extra level of detail is tangible-if you know where to look-and it's effectively free in performance terms, sometimes better than free. Like Frame Generation, Nvidia has unlinked Ray Reconstruction from DLSS, but if you're using ray tracing in any form, in any compatible game, based on my experience, flip that damned switch. That makes Ray Reconstruction an absolute must for high-end GPUs running ray tracing. the World might not immediately come to mind as a typical example of magical realism, it most definitely can be considered as such. But with Ray Reconstruction enabled that leapt up to 103 fps simply from ditching that denoising step. While Edgar Wright’s loveable Scott Pilgrim vs. On Overdrive, with the path tracing tech demo at 4K, and with DLSS set to Quality and Frame Generation set on, I was getting 69 fps on average. With that step gone, I was seeing a serious boost in performance with the RTX 4090 I was using to test the feature. Where the path tracing mode of the game needs a lot of GPU resources, it utilises a lot of denoisers in the pipeline. ![]() Ray Reconstruction, while still part of DLSS, is not necessarily about increasing performance, but it certainly does at the high-end. The temporal nature of denoising can add in weird graphical effects and ghosting, and then the final blending stage can smear away detail from a scene. That's how you get the cleaner, not-so-speckly final image in something like Cyberpunk 2077.īut it's still just another layer of fakery, with Nvidia itself calling this accumulation of pixels in a temporal fashion across multiple frames "stealing rays from the past." That's fine for a static image, where that accumulation of pixels will be more or less the same from one moment to the next, but in motion is where it falls down. First, they track and group pixels temporally across multiple frames, essentially allowing for more samples, then they use neighbouring pixels from these representative samples, and finally interpolate from them, essentially blending them together. These so-called hand-tuned denoisers use two different methods to fill in the blanks. So, from there it's the job of the denoisers to fill in the missing pixels that didn't result from the firing of those few specific light rays. The final blending stage can smear away detail from a scene.īut this noisy image is far from what you want the final look of your game to be.
