Can anyone explain what is dlss and what it does? i really don't know

Its like a better version of anti aliasing.

essentially renders the imagine in a lower resolution and up scales it to the original/ higher resolution.

that means there would be a performance improvements and maybe a slight improvement in looks. DLSS 1.0 was a mess but 2.0 is good.

It's stands for Deep Learning Super Sampling. Super sampling is already a technology that's existed for a while. The basic premise is that you render a much larger image than the screen resolution, and the scale it down to the screen resolution. This has the effect of further smoothing out the polygons, and just sharper detail in general.

 

DLSS, works the same way in principle, but instead of actually rendering the much larger image, which would require more power, it uses AI to to upscale the actual real resolution, and then scale it back down. This means that the GPU is still working basically the same amount, with the same performance, but you still get some of the effects of traditional super sampling, i.e. a better looking image overall.

 

As the AI gets better, the greater the effect, and DLSS 3.0 can practically you at 4K resolution from a 1080p sample.

DLSS means using the Tensor cores to create extra pixels for a lower than what you wanted resolution image to create a higher one, i.e. Super Sampling. This means the GPU doesnt have to render the whole image at native resolution to begin with, saving effort.

 

This does mean losing graphical quality to some degree

As far as I know, it works on just some games, not every game has it.

Yes. It's graphics card specific, so support has to be enabled manually by the dev.

Essentially, DLSS is the opposite of DSR. DSR renders image at higher resolution and scales it down to whatever native resolution display user is using. DLSS is hyped as this miracle algorithm that renders almost nothing and then pulls details out of thin air. Which is BS and can't be done. You can't ever pull details out of nowhere. We had some speculations here on LTT how it works and best theory by someone (sorry, don't know his name) was that DLSS is optimized in such a way that it selectively decides what is rendered at full detail and what at lower so that detail is kept while performance goes up because it doesn't render scenes in full detail for every frame, but cleverly filters out some things while keeps thos ethat define detail and sharpness.

It works well enough to fool human eyes. Even though you're technically losing half the data you're not losing half the details because DLSS fills in the gaps in a way that fools your eyes exceptionally well. I still don't like it very much because, just like MSAA, it makes everything look a little bit blurry.
