Nvidia says DLSS 5 comes with a 50-60% performance hit, which makes me wonder what we're doing here

You thought ray tracing was bad...

The very bad news is, Nvidia says turning DLSS 5 on will currently reduce performance by 50-60%. And that’s across the board—no matter the game.

    Dlss was originally an anti aliasing technique (its in the name) so it has originally been a performance hit. It was casual change and marketing that decided that upscaling from a lower resolution was the norm.

    DLDSR is essentially what DLSS 1.0 was

    If youre upscaling from a lower resolution, thats no longer the SS in DLSS (super sampling)

      DLAA is the anti aliasing only. DLSS was always ai upscaling with anti aliasing as a first pass, literally Deep Learning Super Sampling.

      DLSS 1

      The first iteration of DLSS is a predominantly spatial image upscaler with two stages, both relying on convolutional auto-encoder neural networks.[31] The first step is an image enhancement network which uses the current frame and motion vectors to perform edge enhancement, and spatial anti-aliasing. The second stage is an image upscaling step which uses the single raw, low-resolution frame to upscale the image to the desired output resolution. Using just a single frame for upscaling means the neural network itself must generate a large amount of new information to produce the high-resolution output, which can result in slight hallucinations such as leaves that differ in style to the source content.[13]

      Thanks!

      I’ve got a 4070 super now, but other than that I always had AMD. So just never really paid attention to it.

      Definitely seems like the my first Nvidia GPU is gonna be my last tho
