DLSS 3.5 - Better Pathtracing for Free

This video is a paid promotion for Nvidia. In it, I investigate Ray Reconstruction - which is DLSS 3.5's trick to preserve more information from path-traced scenes.

I think Alan Wake 2 was made with ray tracing in mind because of how big the role of light and shadow is to the game's theme. Maybe you can check that out? It also uses DLSS 3.5 with ray reconstruction and everything.

I am with AMD for their openness and linux compatibility. But I do get FOMO everytime I see NVIDIA release better tech and I need to wait for AMD to catch up

[thecuriousone]

dude your videos are so simple to understand it makes me feel smart

[supremty]

I love your deep dives into tech like this, you have such a good way of presenting the information!

1:23 I love how similar this looks to a picture taken from a DSLR at high ISO. Goes to show how accurately this technology mimics reality.

[DeSinc]

small correction on 11:35, DLSS 3.5 does not always include all the parts, and older 20 and 30 series cards can run DLSS 3.5 with no access to frame generation. DLSS 3.5 refers as you said to the newest toolkit of DLSS options, including the new ray reconstruction all on 20 and 30 series GPUs, but only 40 series can turn on frame generation.

Reallly think NVIDIA should rename their thing to like

"NVIDIA DL-Game Enhancement Suite"
With DLSS Super Resolution, NVIDIA Frame Generation, and DLSS Ray Reconstruction, NVIDIA Reflex, and heck, maybe even NVIDIA Image Scaling as the named features within it.

just found this channel
this feels like digital foundry but denser and faster and more self expression
loving this awesome stuff

[loutrepolemique]

It'd be really interesting if you could make a similar analysis in Alan Wake 2 which to me, seems like an overall better implementation of raytracing and ray reconstruction.
Thanks for this video anyway, always a pleasure to watch your work !

Upgraded recently to RTX 4080 laptop and the performance in all games is just insane.

[ricky_pigeon]

"better performance for free" for developers, not for players. it's put in game requirements now. funny how this turned out.

[Zolbat]

What I find interesting is that I never liked sharpening on the monitor, but when I used it in VR (in DCS using reshade), it was an absolute game changer. Everything suddenly looked a lot more realistic and - well - sharper.

Honestly for all the hate on Nvidia, it is easy to forget the massive investments and advancements they are bringing to AI and gaming. Whether people like it or not, this is the way gaming and many industries are headed and Nvidia are way ahead

[cocobos]

Man, this video is so good. The in-depth is so much better than any other video I've seen! I just found your channel! Easy subscribe!

[Soraviel]

This is absolutely insightful of the inner working of DLSS 3.5, great stuff bro.

[Scorch]

I appreciate that you took the time to point out that while the path tracing and ray tracing methods available can certainly look superior, they may obstruct the thematic tone or style artists are trying to convey, as I think that's going to be a difficult line for devs to walk until everything is completely compatible with that tech.

[cryrpwastaken]

one of the most serious toned videos 2kliksphilip has put out and i love it

[_KOANS]

I'm playing on a 4070 with path tracing. When I use dlss 3.5 the reflections and qualities are definitely better, but very ghosty. Without RR the quality is slightly less clear, but DRAMATICALLY less blurring. I've been playing PL without 3.5 because the ghosting is just too much. Hopefully this can be fixed soon as most people simply don't use it. Very informative and great video.

[LukeFlegg]

Wow this is impressively thorough. Really apprecaite it, thanks

This game went from crysis pc melter meme to literal rendering sandbox. Its crazy how much the look of this game changed from release and with how much you can change it now. And its almost all lighting related
