Hi guys I saw many games got into graphics menù the Dynamic Resolution option or Scaling Option, where you can set the min % value of native resolution. But i want to know if the scaled resolution aspect can be compared to the native version of the same resolution. For example if i use a 4K monitor and i set a Dynamic Resolution / Resolution Scaling to 50%, i should have a 2K ( theoretically sightly highter ) resolution upscaled to my native 4K monitor resolution, THIS IS RIGHT ? If yes this is comparable to a real 1440p looked in a native 1440p monitor ? Or the scaling effect compromises the image quality ? #1 · Dec 22, 2020 Hi guys I saw many games got into graphics menù the Dynamic Resolution option or Scaling Option, where you can set the min % value of native resolution.

Same is backwards, if you're at 4k and run 50% scale you'd be at 1920x1080. It'll look like crap. #3 · Dec 23, 2020 1440p running on a 4K monitor won't look as good as 1440p Native, unless you're using DLSS2.0, and depending on your standards for motion handling. I'm betting a lot of people would also rather have a Native "3K" (2880x1620) resolution display than run 75% render scale on a 4K monitor. Of course to that I say there's no reason developers can't target Native 4K on low settings and still end up with a visually impressive and functionally superior game (e.g. any time you're using iron sights it's way easier to aim if you have high render resolution). #6 · Dec 23, 2020 (Edited)

No i dont wanna use a 1440p resolution in a 4K monitor. Im speaking about the scaling feature in games options, so a 1440p upscaled in 4K

In 4K some games is not possible to find a good compromise to keep the 60fps, especially with AMD Graphics card, also with 6800XT. In last two Total War games in 4K i should decrease the image quality in medium that is a quality destroyer preset ( High preset is already very different to Ultra ). In Cyberpunk with medium settings still not enough to keep 60fps in 4K. 0 Reply #4 · Dec 23, 2020 Fist off, "2K" is not a thing. There is 1080p, 1440p, and 4K. 2K is a meaningless term so try to avoid using it. If you were using a 4K screen and you set the resolution scaling to 50% then your game would be running at 1080p, not 1440p. The main difference vs 50% res scaling vs just setting the res to 1080p is that you can use there are often other upscaling methods that work better with res scaling like TAA so resolution scaling should look a little better in the end. So yes the difference between 4K at 100% scaling and 50% would be easily noticeable, about as easy as it is to tell 1080p apart from 4K. if you set the scaling to 80 or 90% then it's not very noticeable. #5 · Dec 23, 2020 (Edited) Excuse me guys, i dont understand a thing. 4K = 4*1080p ( or 400% of 1080p ) So ... Why 50% of 40K become 1080p ? This should be 25%. Ok maybe you are telling me that the % scaling is applied to both dimensions, so if i want reduce to "around" 1440p i should use the 70% of scaling, this is right ? If yes i should see an aspect comparable to a 1440p native image ? #7 · Dec 23, 2020 Yes, that 50% scaling is applied in two dimensions. You then have 50% * 50% = 25%. If you want 1440p you need 66.7% scaling. You can calculate things by looking at the pixel counts of just one of the dimensions: Code: 4K = 2160p ---> 1080p 1080 / 2160 = 0.5 = 50% 4K = 2160p ---> 1440p 1440 / 2160 = 0.667 = 67% Show more replies 0 Reply #10 · Dec 23, 2020 The difference is that game engines can keep the HUD UI in native resolution and only render the game scene in scaled resolution. This is impossible if using a lower native res, so all UI also have to be scaled and will look blurry with scene. Another option is the dynamic resolution scaling used in Shadow Warrior 2, where screen is broken into 5 zones with the center zone being the largest and rendered in native resolution, while the sides are at lower resolution. #12 · Dec 23, 2020

Thank you for answer, but speaking as global sharpness, the resolution scaled image in game menù can be better or same to a lower native resolution ? Speaking more simply, If i use a 75% of scaling of my 4K monitor ( so 2880x1620 ) i'll got a better sharpness compared to a 1440p native image or no ? Show more replies 0 Reply #13 · Dec 23, 2020 Ahh I see. What's ur budget? What county are you in? The higher the resolution scaling the sharper the image #16 · Dec 23, 2020 1440p upscaled is not worse. Cyberpunk uses heavy TAA which causes some artifacts, especially with resolution scaling but it's different for every game and the look of it is subjective. There are also other sharpening techniques that still apply when you run at a lower resolution without scaling like Nvidia image sharpening so it's not an ideal comparison anyway.
