In the game's graphics settings menu there's options to lock the framerate to max of 60, 120, or 144. You may have it set to 120.

But yeah, thanks for doing the comparison test. To me DLSS 2.0 is awesome and I can't wait to take advantage of it in games that support it once I upgrade. I'd much rather use DLSS 2.0 upscaled from 1080 to get better performance, than the slightly better image quality of native res. Honestly I don't even think the image quality difference is noticeable when you're actually playing the game, but you can bet your ass the boost in framerate is.

Damn, I didn't even think to check for that. I forgot that option existed until you mentioned it. :lol: I have a suspicion it will just move from 120 to 144 locked though, I'm already at 100+ fps with DLSS at 4k at least in that area.

Yeah to properly test at 1080 you would probably need to gimp your 8700 to create a bottleneck by disabling cores and reducing clock speed so that you peg CPU utilization to 100%. That would for sure drop framerate a good amount even with your 2080 Ti.

You probably don't have the time to bother with that but if you did I believe the Intel Extreme Tuning Utility could do it.

Pfff... man I'm gonna continue to eat this ice cream cone instead. Sorry Pauly. :lol:

DLSS is magic, I played through Control with the base resolution set at 1920x800, still looked good.

DLSS doesn't touch dynamic resolution scaling, that might be an in game setting instead if you're seeing that.


In Death Stranding there is a consistent fps increase going from no AA to DLSS, which is expected, it's using a lower internal render. Most people will play with some type of AA so that difference is going to grow.



Also this wasn't intended to be an image quality comparison but a performance comparison, but if we're going to do that, then no-AA comparisons should be done in a video. Still shots doesn't even come close to showing the eye bleeding artificats running a game without AA shows. DLSS 2.0 looks comparable if not better than a native 4k image with AA applied. Every AA method will smooth out pixels to some degree, so that "sharp" look isn't going to be there with TAA,SSAA, DLSS, etc.. but DLSS 2.0 gives you back that comparable native 4k image without the performance hit.

It specifically says in the game settings under dynamic resolution "controlled by dlss" when dlss is enabled, with no options. When you disable dlss, you have 3 options. That indicates to me, that dlss indeed does touch dynamic resolution. Otherwise it would simply say disabled with dlss as it does for the nvidia shaders.

All I am saying as there may be other changes unknown to us that dlss controls, changes, or effects.

Mangler Sep 11, 2020 01:20 PM

2.0 doesn't have support for dynamic res, it's one of the new features of dlss 2.1.

I dont quite understand how it works....AI machine learning what?

So if it was to be implemented in some fashion on a non-nvidia card how does it go about doing its work?

Technically it doesn't require it. They could run it on CUDA cores but they have chosen not to.

It works like TAA, it then use's a pre-trained AI model to help improve the TAA. That AI model is trained with images of the game with 64xSSAA. It use's that information to try and improve/correct the TAA image. This can result in it filling in detail that is lost at the native render resolution. Leading to an output image close to, or some times better than, a native resolution render of the image.

If this was implemented outside of nVidia cards, you would likely use DirectML or another compute shader. Control, before it was patched to DLSS 2, had an implementation of DLSS that didn't use the Tensor cores. Was still software locked to RTX hardware however.

I assume DLSS works with any resolution?

For example, my 3840x1600 oddball 21:9 resolution? All I ever see is the usual 1440P/4K DLSS examples, but I assume it works for anything...

I was thinking about it today as I was going through 3080 benchmarks because it requires scanned images to work. So I started thinking about how that would work for ultrawide resolutions if they scanned in 16:9. And if it DID work, does that mean each game would need their own updates to get it to work with new scanned images?

It seems like some of them might work, but I haven't come across much.

Since Control launched in 2019, the game's DLSS support has also been extended to support aspect ratios outside of 16:9 (such as 21:9), as confirmed by KeithPlaysPC on Twitter. This is great news for users of ultrawide displays, and gamers who use other non-standard aspect ratios. Kieth also wrote a piece on Control's DLSS support on WCCFTech, which is worth reading if you want a second opinion.
Has anyone here tested any of the DLSS games on 3440x1440 or 3840x1600?

SIrPauly Sep 16, 2020 02:44 PM

Dlss 1.0 had limited resolution support, Dlss 2.0 did get rid of that limitation, from my understanding. I'll do a Google search to make sure.

As I said earlier in this thread, I played Control at 1920x800 DLSS:ed up to 3840x1600.

And it still looked comparable to native 3840x1600.

DLSS = Magic.

Awesome! I did see a single link saying Control was added to UW support, but haven't seen anything for any other games.

Have you tested anything else? Thanks! :)

KAC Sep 16, 2020 11:16 PM

Will Metro be updated with DLSS 2.0?

SIrPauly Sep 17, 2020 03:30 PM

Many are hoping!


I just learned Crysis Remastered is getting Rtx Raytracing and Dlss:

Metro, dlss seems to work in 21:9, but metro has the old, non-magic version of DLSS.

i have, posted some scores over in the benchmark thread(tomb raider and control)

So I gave fortnight RTX a try and for whatever reason, I was getting better performance with DLSS on than off.

4k all RTX settings maxed, DLSS at the highest quality was about 28-40fps

4k all RTX settings maxed DLSS off was about 43-52 fps.

Not sure what the deal is there but it also crashes a lot with RTX on.

Megaman Sep 20, 2020 11:42 PM

Any chance you were simply running Epic Reflections versus all RT Effects and confused the two when noting performance?

Set DLSS to off but when I hit apply, it moved it to the 2nd one down. I changed it several times after noticing and 2 out of 5 wound up applying a different setting.

Exposed Dec 8, 2020 12:35 PM

Bumping this up for SuperGeil


One image is native 4k, the other is DLSS 2.0 4k. Can you tell which is which?

































































Nunz Dec 8, 2020 12:49 PM

1st: DLSS on first pic

2nd: DLSS on first pic

3rd: DLSS on second pic

4th: this one is ... harder. i will say they look essentially identical. if i took the time to really sit there and stare i could probably figure it out but i dunno. i'll throw a random guess .. dlss on 2nd pic

The first batch of pics is a little weird because they're not identical with the character being in a different standing position. I don't think anyone can take away from DLSS in photos; but still-shots don't tell the whole story.

Exposed Dec 8, 2020 01:10 PM

You got 50% correctly identified but won't reveal which sets yet. But you got a 3080 bruh, go load up some DLSS 2.0 games and see for yourself. Metro Exodus doesn't count because it's the old DLSS 1.0

If you plan on playing Cyberpunk I think you're going to appreciate DLSS 2.0 alot more as well.

Nunz Dec 8, 2020 01:15 PM

Cyberpunk will be my first time using DLSS2.0

PM me answers. I'm assuming it's the first batch of pics. I change my answer for the first batch of pics .. DLSS on 2nd pic :bleh:

Only reason I haven't tested out DLSS2.0 is because there's no games I would want to play that have it..

SIrPauly Dec 8, 2020 02:40 PM

Thought I would chime in: Dlss 2.0 would take the input of 1440p and Ai reconstruct the image to 4k using 16k for the training.
