DLSS 5 - photorealism lighting and materials

DLSS 5 introduces a real-time neural rendering model that infuses pixels with photoreal lighting and materials. 3d models are not altered, it uses AI to completely overhaul a game's lighting in real time, applying photo-realistic illumination, subsurface scattering on skin, more convincing hair rendering, and improved ambient occlusion to existing game worlds without changing geometry, textures, or materials.

It looks incredible ... worth noting that it was a development preview and Nvidia were using TWO 5090s to run the demos .. one of the cards to render the games and the second 5090 to actually do the DLSS5 processing.

Of course it will be rolled into something that is usable on a single card when it's ready for release but I would guess you'll have to buy one of their 60xx series cards (when they are available) to get it and probably one of the higher-end ones at that, to get good performance.

Might be a VRAM eater looking at it, so the next 6000 series mid/low tier cards might not to run it with less than 16Gb as a "finger in the air" guess.

I'm also not 100% sure I want "photorealism" for the FPS games I play, might be a bit too much realism

Looks like it tended to fk up the lighting and shadows, went for the 'brighter & more saturated = better' look like people do when showing off TVs in the shop.

Some of it was quite impressive but it's a bit like a lot of what's in UE5 - looks shiny in the demos but there's a lot of horrible compromise involved if you want it to do your own specific thing that doesn't fit their idea (as I hear from the developers who have to fight its codebase).

More layers of “stuff”

If they just made optimised high quality content to render in the first place…

I’m not sure this kinda approach is sensible long term.

I assume a multi-gigabyte model sits alongside this tech, and if it gets updated/changed the appearance over time is gonna change.

Plus in 10yrs when the tech is abandoned will older games suddenly look even worse than they should?

Looks like complete dogst. Why would you want to run an AI slop filter over your games? Even their cherry picked examples with dual 5090s look absolutely awful and in many cases totally change the feel of the scene.

It's what people already do to Bethesda games to get rid of the potato faces.

It has huge potential. I watched the Digital Foundry video on Youtube. The faces, clothes and details look great, however the outdoor scenery shots look too bright, lost atmosphere, and were not pleasant to look at. I hope it will be a lot better by the time it is released.

I remember when the 3dFX VooDoo cards came out and everyone was amazed at the leap forward. If Nvidia get it right, this could be a similar revolution. I've been wanting realistic graphics for years and frankly, the progress over the last 20 years has been poor.

Look at the Oblivion re-master for example:

It looks better, but not 20 years better in my opinion.

It runs locally, so as long as you still have a graphics card that supports it, it should be fine.

You're never going to get something approaching realistic graphics without using AI at some point. Either when the game is being made or later, such as this. If older games like Morrowind can be modified to use it, it would be fantastic. Morrowind is considered by many to be the best of the Elder Scroll games, but after playing Oblivion and Skyrim, I couldn't deal with the massive visual downgrade.
