WRT - TW3 Complete Edition Ray Tracing Developer Q&A - Digital Foundry

Q. Do PC and console RT share the same amount of ray per pixel for RTAO? Also do console and PC versions have the same ‘rays per probe update interval’ for RTGI?

A: RTAO is fixed resolution on consoles (800x900 checkerboarded), however on PC it is based on the render resolution setting and is not fixed. Our Global Grid settings are on a relatively even keel between PC and consoles. Local grid is a little different, it is less dense on consoles where we use fewer probes and give more space between each. We have lower shading-rays-per-frame on the console local grid, but because of the reduced number of probes it should come out at a similar rays-per-probe. In addition it is worth noting that classification-rays-per-probe is reduced on console.

 

Tested 2.5.1 in God of War and RDR2 with the best result so far.
RDR2 I run for a long test in Saint Denis and I confirm the lowest trails with aerial power lines, and for last (but not the least) they have removed the sharpening by default. Very good.

 

I don't know. Didn't try RDR2 since it's not installed, but God of War has a lot of flickering on fine lines in the distance with 2.5.1.

2.4.6 still seems like the best one for me to use for both anti-ghosting and temporal stability. A bunch of recent versions don't have the ghosting, but I notice stability issues which are annoying.

 

PSA: DLSS DLL version 2.5.1 completely disables DLSS sharpen in existing games. : nvidia (reddit.com)

 

Oh my God, this is really the good news of the year for DLSS.
RDR2 was one of the worst implementation of DLSS, with a bad quality image, lot of shimmering etc.
I confirm that now the image is super stable with no more flashes and other, with less ghosting expecially in power line trails in Saint Denis. Well done.

 

I read a comment on Reddit saying that swapping nvngx_dlss.dll in Control forces the game to use it's native upscaling instead of DLSS, is this true? And are there other games with similar issue?

 

One of the people working at Nvidia confirmed on reddit that the dlss sharpening is disabled going forward and they will have to use NIS sharpening instead as it's " Superior "

 

Did some testing in Skyrim SE: With more recent versions like 2.5.1, DLSS Ultra Performance isn't useless anymore. It was basically broken with 2.3.9 (it may look more detailed, but it's actually crazy amounts of aliasing and flicker in motion):


Far less bad with 2.5.1:


FSR 2 UP is way more blurry:


Though with regular Performance setting, I'm not able to capture noteworthy improvements on screenshots vs. 2.3.9.

 

In LEGO Builders Journey, DLSS Ultra Performance mode seems to be DLAA now after swapping the DLL to 2.5.1!? It generates significantly more GPU load compared to DLSS quality (whilst looking better than DLSS Q).

 

Interesting. If that's true, perhaps it'll allow us to use DLAA in games that don't have an option for it.

 

Link to the article?

 

Yes, only 2.2.11 works in Control after swapping. With other versions, it looks like bilinear scaling. No, it doesn't seem to happen with other games and Control is the exception. Though RotTR and SotTR have other issues with newer versions, but these seem to be the only titles affected as far as we know.

Btw. narrowed it down to 2.5.1, which is the first version with UP fixed. 2.5.0 was still broken.

 

"updated" has more shader aliasing.

 

It has less right to the non-magnified area.

 

It also glitches the same text as it goes over the B pillar just before they pause it. It's better than before. Which is nice that they show given the video states "keeps getting better". But um... given they never released the previous version for the public for Cyberpunk, kinda of a silly game to use for this.

 

Game will support NVIDIA’s DLSS 3 tech, and will have Ray Tracing support for reflections.

 

For modern pc games no need ray-tracing feature.
