Need help/clarification on how DSR (dynamic super resoultion) should work.

[JG700_Benek]

I've been trying to test the DSR feature to see if it helps with spoting. My understanding of DSR is that it should force the game to render  in higher resolution (4x in my case) and then to downscale it to fit into 1080p screen. Thing is that during my tests the game is not downscaling -first part is working  I get bigger field of view and can see whole plane in menu when in 1080p only part is visible and so on.

My question is if some1 got it to work like its described in nvidia control panel (DSR produces smoother images by rendering the game at higher resolution then downscaling it ) or is it impossible at all and all? If any can paste their setting if they able to use 4x DSR and then get it downscaled.

Do you have interface auto scale turned on or off?

Auto UI is on. The question behind question is how 4x DSR on 1080p screen should look like. On my end it looks like a 4k screenshot dezoomed to 50%. From description I would expect it to be 1920x1080 but with better aliasing.

It should look like a 1080p image with better antialiasing. Is your game set to “full screen”? Or scaling on NCP set to fit it?

honestly DSR requires huge performance cost and provides surprisingly little actual improvement. If your GPU can handle 4x 1920x1080, just get a 4K screen and see the real resolution. It looks way better.

Game is set to run full screen as for nvcp scaling I tried (I think) all options there. Thing is when dsrx4 is used the terrain looks flawless no jaggies at all same for trees and so on but the planes seems smaller to me and i feel like I have bigger field of view. I dont want to play at 4k mainly because of being used to high refresh rates. Was wondering if its possible to use dsr for antialiasing but keeping the 1080p contact visiblity. Seems its not possible or something is wrong with scaling on my end since you also say it should look the same as 1080p but for me it looks different.

The trouble is that 4x DSR is giving you exactly the same frame rate cost as a 2160x3840 monitor but without the sharper image

...except that IL2 doesn't dynamically scale the contact size, which can lead to spotting issues as is well attested from this thread (distant contacts are 1px, and unless you've got a very large physical monitor size, 1px is barely visible in 4k):

Not sure if DSR would give better results though.

I don’t know if IL-2 actually works that way, using pixel-sized sprites. Last I heard it uses a scaling algorithm for the LODs but they don’t remain at a fixed pixel size, they just get smaller and vanish with perspective. What you can see on 1080p is a sort of bloom from the LOD bleeding onto other pixels which can make it more noticeable but also less distinct. On a 2160p screen the distant contacts appear as very sharp distinct specks, it’s possible to even ID them quite far away so there a bit of advantage. The trade off being that they’re tiny. But this might mean that DSR gives you the worst combination because you’re forcing the resolution smaller without getting the actual output on your screen. IMO it’s always better to match the native res of your screen. Don’t upscale or downsample. The image will look better and the game will perform better.
