DLSS 2.0

[gravdestroyer]

If I have a GPU that uses DLSS2.0 will I be able to play games in 4k on my 3440x1440p monitor? It sounds like a dumb question but with all the talk about DLSS 2.0 I thought it was worth asking the question.

Thats not what DLSS does.

 

 

And you have been able to run at higher resolutions through various solutions, and then downscale to the resolution used for a while now.

My understanding is that DLSS creates an image at a lower resolution then upscales to a higher resolution.

 

The idea being that it is faster to create at a lower resolution and upscale than it is to create a higher resolution, thus resulting in better FPS.

 

I think the question is more, is there any benefit to running a 4k resolution on a 1440p monitor...can you gain anything from that? Does it improve the image quality?

 

I don't know the answer, look forward to anyone who does letting us know.

Yeah, but it doesnt do what OP is asking if it can do.

 

Running a game at a higher resolution and then downscaling has been a thing for a fairly long time at this point. Usually because it offers some improvements to visuals.

 

Also known as supersampling.

What GPU  and what refresh rate? And what Game?

 

Generally 4k RTX gaming is limited to the 2080 ti and 2080 with DLSS 2.0 improving performance a bit.

 

However, if you want to turn RTX off and don't plan on going above 60 Hz, then you can use a 2060 with DLSS 2.0 on.

 

Look up YouTube videos.  You can see it there.

Doesn't it?

 

I thought that is what it did, as it is Deep Learning Super Sampling, it upscales to a higher resolution.

 

I thought he was asking can he set the upscaled resolution to 4k on a 1440p monitor to gain some improvement.

 

Thank you for the answer on downscaling offering some improvement - i.e. a 4k generated image viewed on a 1440p monitor, I was not aware of that, but it is good to know moving forward.

well why not actually try it you have the GPU (which you didnt mention and the one in your signature doesnt support it)

I said downsampling a down scaling. Not upsampling. 

 

DLSS attempts to upscale. Not downscale, which is what OP seems ro ve reffering to.

That aside for a moment.

 

I am confused, not that I doubt you, but how can there be any benefit from downscaling?

 

4k is just the number of pixels on the screen right it isn't antialiasing or any other type of technique to improve visual quality? It just more pixels on the screen, and therefore more pixels within each 'area' that you are looking at, which increases the quality of the image.

 

If you down scale to 1440p from 4k, you reduce the number of pixels that you are looking at, how can there be a visual improvement?  How can the image be any different to a 1440p generated image?  The image must spread out again to 1440p which would be the same as a 1440p generated image?

 

As I say, I accept you are right, but I don't understand how it can work...I assume that I have a misunderstanding of something here.

or in other words he will select 3440x1440 on the game settings as his resolution and enable rtx/dlss 

 

then what will happen is that the GPU will render in e.g 2k (im am not sure about the exact percentage of downscalling and I am too bored to google it) and "DLSS it"  to 4k increasing the FPS compared to DLSS off... so basically that's what OP asks (and I believe wishes to be true)

because the image is created by a 4k source material. which would help with dealing jagged edges or other small visual improvements.

well no. it will render at less than 2,5k (his current resolution in 16:9) then being upscaled to 2,5k using DLSS.

i cant tell where you get the "compare FPS" from. 

 

 

he is fully capable of doing  what he ask with an increased resolution scaling, or super sampling. no DLSS required. If DLSS can assist in that matter, i dont know.

This is wrong, the exact downscale resolutions have some variation but DLSS is trying  via AI to reproduce a 64xSS 4k image

 

what happens is that it renders usually at 2k (which I mentioned on the post you quoted that I wasnt sure about the exact figure and was bored to google it yet you tried to "correct" on that figure lol but as it turns out I was right anyway and that its 2k in most of the games) and then it "DLSS it" to 64xSS 4k!

 

I use the self made term "DLSS it" because it doesn't exactly upscale it per se it has already code that can predict how the pixels should look like at 64xss4k and "attaches" that prediction on screen. (upscalling is just cloning lines of pixels to an image) 

 

That's exactly what OP asks I think you got to a point where you try to add just unnecessarily confusion in order to insist on your opinion.

that depends on what you set the DLSS to do. not all of them upscale to just 4k. it depends on the target resolution on the output. 

 

which it will then proceed to render a lower resolution image, which it then proceeds to upscale via DLSS.

was bored to google it yet you tried to "correct" on that figure lol but as it

i gave no specific figures other than to adjust the output resolution to the 16:9 variant of his display. that being 2560 by 1440p. aka 2,5k. 2k being more similar to 1920 by 1080. 

 

i gave vague pointers as to the render resolution before upscale was lower, then being upscaled via DLSS to the target resolution. 

 

he may enable DLSS for it to do as described above, but DLSS, afaik, wont make a 4k image, that will then in return be supersampled down to his target resolution. 

 

i may have missunderstood a bit as your figures didnt align with the output resolution of what OP is aiming for.

m8 you go here and there jumping around on details adding confusion for really no reason. 

 

 

bottom line: OP has a 1440p monitor, wants to play at 4k and wonders if DLSS is going to help...


he has a 1440p monitor alright, then he needs to set the game (e.g shadow of the tomb raider) at 4k can he do that? yes he can.

 

Now can DLSS help to boost his performance ? yes.

 

If he just set the resolution to 4k he will get something like e.g 45 FPS

 

If on top of that he enables RTX/DLSS he will get something like 55 FPS. 

 

 

So the answer to his question is YES dlss will help him play at 4k at better frame-rates. 

 

 

He didnt ask about technicalities on how it will work he asks if it can help and it can no need to add confusion.

DLSS upsamples lower resolution up to what you have native (say 720p to 1080p). What you're looking for is DSR. It runs games at 4K and downsamples image to whatever resolution monitor you have (4K to 1440p)
