Nvidia DLSS 3 antialiasing discussion

[yamaci17]

I wonder if DLSS 3 can help with this? i.e. what of you lock your frame rate at a level comfortably below your CPU's limits but then use DLSS 3 to get it back up to something reasonable. Would all that idle CPU power help to reduce the SCS?

I mean compilation stutters are not happening due to frametime budgets or CPU performance budgets... I think the engine practically stops rendering for a microsecond. I don't think what you suggest would work.

I however wonder if AI can be taught to "discard" stuttered frames and fill them with a normal, interpolated frame instead. Of course this would, once again, need some kind of buffer so AI can see forward, so more input lag. But there definitely is a potential solution to stutters there.

But stutters are less evident on more powerful CPU's by most reports so I would have though reducing the CPU load should have some impact at least, even if it can't eliminate them completely.

Has there been any analysis done on FG quality at various raw fps values?

LTT blind test video few posts ago is the closest match, DLSS3 was ranked worst in image fidelity regardless of FPS

Can you use a frame rate limiter to limit the framerate to say 70fps and then use DLSS3 to double it? Obviously that's probably a waste if you can get to near 144fps without frame generation anyway. Although if you throw on max DLDSR I assume you could restrain even the 4090 enough. DLSS3...

Not on Gotham Knights according to DF.

A faster single thread Speed can make a stutter length shorter - Like 150 down to 100 MS, but it will Not make them less frequent so to speak.

Wait what, it actually manages to create artifacts even when interpolating simple video?!

It seems to create artifacts in situations where it's difficult to find the optical flow vector between two consecutive frames, no matter how simple video is. But yeah, the artifacts quite noticeable than I expected.

NVIDIA Frame Generation reportedly works with AMD FSR2 and Intel XeSS - VideoCardz.com

AMD FSR 2.0 + Frame Generation = FSR 3.0? A very interesting piece by Igor Wallossek from Igor’sLAB on FSR 2.0 and XeSS supporting NVIDIA Frame Generation. According to the article posted this morning, the backbone of NVIDIA DLSS 3.0 technology, known as Frame Generation, reportedly works with...

For a short second I believed FG was working on AMD hardware which support FSR2 and Intel cards....

that would be the idea, but as such it's the most useless news. I shared it 'cos I found it in a well-known website but it's nonsensical.

This is the original article, which shows many details, like the performance gain obtained with this frame generation technology by nVidia:

AMD’s FSR 3.0 emulated: Frame Generation with DLSS 3.0, FSR 2.1 and XeSS in benchmark and quality comparison | Page 5 | igor'sLAB

We have already reported in detail about NVIDIA's DLSS 3.0 and the option to generate and insert additional frames via frame generation. AMD had recently announced a similar feature and FSR 3.0…

I still kind of hope that some mod/hack can enable it on 30xx since the Optical flow processor is here (granted not advanced enough , per nVidia, who knows).

It was already in Turing actually

nVidia updated the optical flow documentation with performance numbers for Turing, Ampere and Lovelace: https://docs.nvidia.com/video-technologies/optical-flow-sdk/nvofa-application-note/
Ada is up to 3x faster than Ampere and needs only half the time for interpolation at fixed clock rates.

And looking at the FSR 2.0 implementation Cyberpunk and Forza 5, FG without upscaling looks so much better.

Which grid size does DLSS 3 use?

It's DLSS Super Resolution and Frame Generation now rather than DLSS 2.X or 3.
Whatever it uses has to be compatible with 4x4 because it's been made to work on RTX 20 in some games at least

I am aware of that. I am of course referring to FG, as DLSS 3 is the name Nvidia created for it.

Got a source for that? And with source I mean not some random guy from Reddit. I've never heard of FG running on Turing aside from a guy on Reddit who did not even provide solid proof.

DLSS 3 is the name NVIDIA made for combination of DLSS FG, SR and Reflex, not a single feature. DLSS Super Resolution is literally the new name for DLSS 2.x, DLSS Frame Generation for that specific feature and NVIDIA Reflex for that specific feature.

I was under the impression there was a mod guide, can't find it now so must have remembered wrong.

this is so huge -as the author's mention, this mod opens the door for using in other great recent games- that while this video has been shown in the DLSS thread, I decided to add it here 'cos the video's author mentions the issue of Skyrim being a single threaded game and the draw calls issue associated with it, and details how DLSS3 is going to solve that problem. The video should start at the very moment -7:10 mark- he mentions that:

Instead of not questioning as to why a mere simple scene with a bunch of NPCs and no apparent complex geometry only becomes CPU bound at 74 FPS on one of the highest end CPUs in 7950x, be happy to hail Frame Generation as a solution instead.

Great!

Bright Memory Infinity got a patch reducing the latency with FG:

Hello everyone! We've released a new update just in time for the release of the NVIDIA RTX4080.
The input lag after turning on DLSS3 has been reduced from 38ms to 27ms.
