Nvidia DLSS 1 and 2 antialiasing discussion *spawn*

DLSS & RT support - UE5

Thats ingame isnt it? If so this game and Avatar stand tall above anything else imo. For Instinction, UE5 at its finest.

Crysis Remastered Trilogy: Raytracing, DLSS vs. TAA

Crysis Remastered Trilogy: Raytracing, DLSS vs. TAA

There's no mention in the piece if they were using the latest updates released this week, I would assume so but it would be nice to get confirmation. Particularly in the case of Crysis 3, which received a DLSS update that supposedly improved the ghosting on vegetation - albeit they mention it, but don't really show comparison images where it's visible.

They also seem to have mixed up the post-processing TXAA vs DLSS image comparisons, at least going by their description of how inferior DLSS is when zooming in with the bow and DOF is applied - yet their image comparisons show the exact opposite.

DLSS vs. TAA

So is TAA considered a rival to DLSS

No. TAA is the base temporal AA method that DLSS replaces.

 

[Davros]

O.k thanks, I thought it replaced all types of AA

DLSS requires motion vectors, which only temporal anti-aliasing solutions can provide.

Let’s start with DLSS. NVIDIA’s upscaling tech is incredible in this game. Not only does it improve performance, but it also offers superior anti-aliasing. This is truly one of the best DLSS implementations, and we highly recommend using it. Not only that, but EIDOS Montreal has included a DLSS Sharpening setting so that PC gamers can adjust it. Truly awesome stuff.

Grabbed Severed Steel today. Game is HARD, but it supports DLSS with an “Auto” quality option and Raytraced reflections. Very cool frantic game.

It’s also ue4 so the tool that lets you dig into hidden settings probably works.

 

[PSman1700]

Looks really nice, never heard of that game. Ray tracing seems nicely implemented aswell.

A different opinion on DLSS in GOTG:

Usually, DLSS doesn't fool you when it comes to image stability, but it just doesn't work in Guardians of the Galaxy. On the contrary: the image stability is already worse with DLSS on "Quality" in all resolutions than with the TAA of the game and that is not convincing in this aspect either. Some objects are smoothed absolutely flawlessly with DLSS, but even DLSS on "Quality" flickers visibly more even in Ultra HD than without Nvidia's intelligent AI upsampling. If a more aggressive DLSS mode is set, the flicker intensifies accordingly.

This is the biggest problem with DLSS in the game. But there is also a second major construction site: DLSS “got worse” also in GotG graphic errors. They come from the game, but are only slightly noticeable with the normal TAA. In fact, the characters in the numerous cutscenes like to struggle with ghosting. In addition, the detailed hairstyles of the characters are not shown very cleanly. With DLSS, both effects are exacerbated. This is not a problem when playing, but it is in the sequences, because the ghosting is immediately noticeable. Here too, lower resolutions and more aggressive modes make the problem worse, but in Ultra HD it is already well defined with DLSS on "Quality". The same applies to a violent moiré effect in the many grids that the player walks over again and again. These are generated by the game itself, and TAA also has to struggle with them accordingly. But DLSS additionally intensifies the effect.

A quasi-standard construction site is incorrectly set mip-map levels at DLSS. As a result, the game does not use the Mip-Maps for the target resolution, but only those for the rendering resolution. As a result, some objects are displayed in less detail than the native resolution, while other details are completely lost. This only has a small impact on the image quality, but it is still a negative point.

So the problem with Severed Steel is I'm basically cpu limited in the DX12 mode, which is the only way to enable DLSS. In the DX11 mode performance is WAY better. Not really surprising for UE4.

Why would they lock DLSS under DX12? You sure that you can't use it in DX11?

Yep, the launcher makes you pick a rendering path and only the dx12 path supports dlss and ray traced reflections.

 

[pjbliverpool]

Also weird that you're CPU limited under DX12. Isn't it supposed to be the other way around?

 

[troyan]

Not on nVidia hardware. Unoptimized DX12 is always slower than the DX11 driver.

There is a new "DLSS Sharpening" slider in today's Doom Eternal update : nvidia (reddit.com)
Also updates DLSS version to 2.3.0. Posted about a week ago.

there’s a sharpening slider in back 4 blood as well.

nVidia said to PCGH that the sparpening slider will (or should) be exposed going forward. Guardians of the Galaxy and this chinese game with ReStir GI have the slider, too.
