Nvidia DLSS antialiasing discussion *spawn*

Shadow of the Tomb Raider was just updated with the lastest DLSS version. Rise as well

• Upgraded NVIDIA DLSS to the latest version.

• New improved shadow denoiser for use with ray traced shadows.

I compared DLSS on vs off in Rise of the Tomb Raider, it cleans up jaggies much more than default SMAA, but is much softer. Probably reccomended to apply some sharpening with ReShade etc.

Thanks! I'm not a huge fan of sharpening and so I'm actually digging this super-clean antialiased look. It doesn't *seem* to be missing any actual detail but I didn't look too closely. How well does it hold up in motion?

 

Looks great in motion, no pixel crawl or ghosting what I could see.

 

Holds up fine but it definitely is not a properly implemented DLSS.
Seems like they've just slapped DLSS on top of ordinary low res output without doing any temporal frame jittering?

Sharpening helps but it's still far from how DLSS should look like: https://imgsli.com/Nzc1Njg/1/2

 

Another comparison with CAS sharpening added, with sharpening I prefer DLSS image.

Maybe because the game doesn't use any temporal anti-aliasing, so without DLSS it has that very sharp and "raw" looking pixels.

 

SOTTR DLSS (re)implementation is much better: https://imgsli.com/Nzc1Nzk

Up there in "better-than-native-with-TAA" territory again.
Static image quality doesn't degrade much between DLSS presets which is what you generally expect from a proper implementation.

There's one caveat though: for reasons unknown they don't allow you to run that fully open sourced FFX CAS on top of DLSS - or even turn it on if you've switched from DLSS back to TAA (or turn on DLSS if you've launched the game with CAS being on).
Aside from there being zero technical reasons for that being the case it does mean that a native+TAA image can be less soft with CAS enabled and this could put it on the same level of detail as DLSSed one.

Well yeah ROTTR was always going to be a bad case cause it has what is essentially very close to a non-AAed image as the base for comparisons.
Still when you switch DLSS presets there it visibly affects texture details which shouldn't be the case in a proper implementation as these should accumulate over frames due to view port jittering.

 

October 18, 2021 - SOTTR DLSS 2.3.2 Benchmark

 

Thanks, wanted to see that. CAS definitely helps, def not the best DLSS implementation but considering some levels are just absolute shimmer-fests even at native 4K, this is probably the best it has ever looked.

 

Deathloop in-game options contain a DLSS sharpening slider. Wonder if this is something planned for future DLSS implementations?

 

You sure about this one? Can't see it anywhere in DL options. The game also disables its own sharpening options if you enable DLSS.

Ability to provide users with tweaking DLSS sharpness option has been added in v2.2 AFAIR.
So far no DLSS game that I know of has exposed that option to end users though.
Most games tend to disable (or just ignore, as with RDR2) own sharpening options when DLSS is enabled which is also a puzzling decision on developers part, especially alongside the lack of DLSS sharpness option mentioned above.

ROTTR's DLSS issues are unlikely to be due to the lack of sharpening option though.

 

My bad, wrong game. I noticed it in F.I.S.T when going over the settings in video timestamped below.

 

Lol it's like they're afraid to actually expose all options DLSS has or something.

 

DLSS patches for Tomb Raider games were pulled from Steam because they had some issues, not necessarily related to DLSS though.

 

SOTTR patch seem to be available, ROTTR one was pulled.
Edit: Or maybe not.

DLSS & RT support - UE5

 

Looks cool, interesting how many games are returning to a dino theme.


Performance is hurting though.
