Nvidia DLSS 3.5 Ray Reconstruction Analysis with Cyberpunk 2077’s 2.0 replace!

Today marks the launch of Cyberpunk 2077’s hotly-anticipated 2.0 replace. That’s all nicely and good, however we’ve got a barely completely different purpose to be having a look on the sport right this moment, as Nvidia’s new DLSS 3.5 expertise has additionally arrived with this newest replace. Today we put the brand new characteristic via its paces with a complete heap of picture high quality comparisons, to search out out precisely what distinction DLSS 3.5 actually makes, and the way it impacts efficiency…

What is DLSS 3.5?

DLSS 3.5 was introduced solely not too long ago at Gamescom 2023, carry a brand new characteristic to the DLSS household – that being Ray Reconstruction. Unlike different DLSS options, together with Super Resolution or Frame Generation, the purpose behind Ray Reconstruction isn’t to spice up your body fee by decreasing the interior decision or including in new frames. Rather, it’s designed to considerably enhance picture high quality when enjoying ray traced video games, and it does this by changing the denoising stage of the render pipeline.

All ray traced video games presently utilise one type of denoising or one other, however Nvidia is eager to level out the present limitations – temporal accumulation denoisers can introduce ghosting, whereas spatial interpolation denoisers can scale back element. No matter the way you slice it, present so-called hand-tuned denoisers do scale back ray traced picture high quality in a single kind or one other.

Not so with Ray Reconstruction – or not less than, that’s the concept. By changing hand-tuned denoisers with an AI community that has apparently been educated on 5 occasions the info of DLSS 3, Nvidia is claiming massively improved picture high quality, as Ray Reconstruction can recognise completely different RT results and intelligently pull out the important thing particulars that may in any other case be misplaced.

In essence, it’s all about ray traced picture high quality. There could also be some distinction to efficiency as we’ll see later, however that is unlikely to be a lot of a change both means. Ray reconstruction additionally works on all RTX GPUs, alongside DLSS Super Resolution, although after all Frame Generation continues to be restricted to 40-series

Test setup

Test System:

We take a look at utilizing a customized constructed system from PCSpecialist, based mostly on Intel’s Rocket Lake platform. You can learn extra about this method HERE and configure your individual PCSpecialist system HERE.

Driver Notes

• All Nvidia GPUs had been examined with the 537.34 driver.

All picture high quality testing was executed utilizing an RTX 4090, with footage captured at 4K/60FPS due to the Elgato 4K60.

Image high quality comparisons

For a full have a look at picture high quality, make sure you watch the video on the high of this web page, each to see extra examples but additionally to see how Ray Reconstruction handles movement. Note: The under are 4K screenshots. Please zoom in utilizing your browser if you wish to enlarge the picture.

Performance

As proven within the video, we noticed small efficiency will increase utilizing DLSS 3.5 Ray Reconstruction. As a reminder, it’s presently solely accessible with RT Overdrive enabled, so body charges are decrease than they may different sensible be with much less demanding ray traced results.

Still, at 4K utilizing DLSS Performance, the RTX 4090 noticed its body fee enhance from 72FPS to roughly 77FPS within the Cherry Blossom Market space. The RTX 3080 10GB additionally noticed a lift of 1-3FPS, from about 40FPS as much as round 42FPS at 1440p utilizing DLSS Quality. I additionally tried the RTX 2070 Super and this additionally carried out marginally higher with Ray Reconstruction enabled, however it was sub-30FPS even at 1080p utilizing DLSS Quality.

Closing Thoughts

Firstly, if you have not already, I’d encourage you to observe the video on the high of this web page to essentially get the perfect concept of what Ray Reconstruction seems to be like – we embody a couple of dozen completely different picture high quality comparisons, specializing in each the constructive and adverse elements to this new expertise.

Undoubtedly although, it’s a formidable innovation from Nvidia and one which has big potential. We noticed quite a few examples the place Ray Reconstruction supplied a reasonably substantial enhance to readability and element in comparison with conventional denoising methods, whereas additionally performing barely higher than stated conventional denoisers.

It’s not good although, as we did discover a couple of points with shimmering and picture instability in sure scenes, notably when involving finer particulars and transferring volumetric or particle results. Ray Reconstruction also can ‘easy out’ a picture barely an excessive amount of for our tastes, particularly when examined at sub-4K resolutions.

The positives far outweigh the negatives nonetheless, and if I had been to begin a brand new sport in Cyberpunk 2077 proper now, I’d undoubtedly play it with Ray Reconstruction enabled. I additionally assume it is honest to think about Nvidia has a robust monitor file of bettering its DLSS options – DLSS 2 was a big leap in high quality in comparison with the unique DLSS implementation, whereas DLSS 3 Frame Generation has additionally improved because it hit the market final 12 months – so hopefully DLSS 3.5 will solely enhance in time.

As a part of its enchancment course of, I’d wish to see two particular issues occur. Firstly, it might be nice to have the ability to allow Ray Reconstruction at native decision utilizing DLAA. Secondly, I actually assume Nvidia (or CD Projekt Red) missed a trick by not permitting the expertise for use with single ray traced results, like reflections or ambient occlusion. Restricting the brand new expertise to solely the RT Overdrive mode actually does restrict what number of RTX avid gamers can realistically use Ray Reconstruction – whatever the truth they’re formally supported, you actually do want a high-end 30-series or 40-series GPU to run RT Overdrive mode as it’s just so demanding.

Regardless, there may be clearly huge potential right here and I’m personally excited to see extra video games introduced with assist for DLSS 3.5. Portal with RTX and Alan Wake II are already on the way in which, however hopefully we are going to get some extra bulletins very quickly.
