DSR and DLSS

[Hi P]

I was reading about DSR and DLSS on reddit and apparently DLSS is only available in 4K resolution, right, a couple users said to enable DSR 2.25 at 1440p to enable 4K and therefore DLSS, but I'm a bit confused by this.

 

1.- Doesn't DSR virtually multiply your native resolution by that factor? which would mean DSR 1.5 at 1400p would be enough for 4K? (2560 x 1.5 = 3840 --- 1440 x 1.5 = 2160)

 

2.- Why do most people leave DSR Smoothness in 33%?

 

Thank you

1- DSR does render the graphics in 4K if you use that said multiplier if you calculated it right, and then it re-render it in 1440p for your screen to be able to show the image. Keep in mind it might lower your monitor's hertz if you use DSR you might want to look at this.

 

2- Because it's the default smoothness and I as well think it's "okay"

I see, so does DSR fake that resolution on any game? or is it an "exclusive" like DLSS?

I believe that is correct. 

 

I tested this on my 4k monitor last night at 4k. I tossed everything to high including the Nvidia works. I get 45-55fps on average without DLS. With DLS I am seeing 60fps-75ps. The image quality holds up. Its not as clean as pure 4k but its close. With the increase in FPS, its legit. 

 

Basically, DLSS is a superior form of checkerboard rendering. It allows GPU's at 4k or 1440p(in the future), to gain FPS by using the tensor cores instead of normal rasteraztion.

Nice, how do you know it'll be available in 1440p? have they said anything about it?

From what I understand the technology should be possible with 1440p. Unfortunately, Nvidia has been vague with all of this.

I know this thread is super old but I just wanted to follow up on it because I stumbled into it as the top link in a google search for DLSS and DSR.

 

The reason for 2.25 multiplier instead of 1.5 is that the scaling factor is for the overall resolution, not just the horizontal resolution. (3840*2160)/(2560*1440) = 2.25

 

You also intuitively did the multiplication twice to show the horizontal and vertical directions. Turns out that 1.5^2 = 2.25.
