Marketing speak makes a lot of tech sound more complex, advanced, or magical than it usually is. This sadly seems to be becoming more common lately in the 3D graphics industry.
(In a similar marketing trend, Nvidia's "Deep Learning Super Sampling" is more like 2x2 grid deinterlacing, not magical AI upscaling.)
- kanwisher 5y agoDLSS literally has a super computer to train models to create accurate AI models to do upscaling for games. you are horribly mistaken https://www.nvidia.com/en-us/geforce/technologies/dlss/ https://www.nvidia.com/en-us/geforce/technologies/dlss/
- pornel 5y ago2x2 deinterlacing is TAA. DLSS goes beyond that, and 2.0 really delivers to the point it looks better than TAA at native resolution.

- kaetemi 5y agoDLSS is TAAU, it's still temporal, based on a 2x2 grid. 2.0 is simply a ML implementation. It doesn't upscale single frames, it doesn't add additional detail to textures. It's "temporal upscaling", which is pretty much just a fancy way of saying deinterlacing.
- pornel 5y agoIf discount the entirety of the implementation responsible for the quality improvement as "simply ML", then it is just fancy a deinterlacing indeed. Just like every ML breakthrough is just a fancy matrix multiplication. But the fact remains that DLSS 2 is friggin amazing: achieving combination of visual quality and performance that was not possible before it, and in some cases it looks even better than rendering at the native resolution. It's solving a hard problem, and does it very very well.
- kaetemi 5y agoYup, it is an impressive tech. My point is rather that most of the marketing speak makes it sound like an _impossible_ upscaling tech, rather than an impressive temporal super sampling tech. I do wonder about the "better than rendering at native", though. In true TV-set marketing fashion, DLSS 2.0 comes topped up with a free sharpening filter to make it look slightly sharper than native renders, by default.
