Well here you go, not a blind test since I have the names, but doesn't need a blind test. In my eyes the 4k DLSS performance is by far the best one but performance drops a bit, 1440p DLSS Q and native 1080p have same fps but the DLSS is apparently better. Retains more details on pretty much everything. Sadly even imgbb compressed them a bit, original images were 25mb, imgbb hosted them at 10mb.
1440p dlss quality is not 1080p btw, it's closer to 900p
Also, I am astonished to report that: they all look meh, I am a bit surprised actually, it's higher res sure, but it retains many weaknesses of the native 1080p image, such as this, which looks to be AO stairstepping
(see what I said about it making things not look that much better than you may think?) (dlss 4k perf on the left, 1080p on the right)
(1440p dlss q on left, native 1080p on the middle, 4k dlss perf on the right) I actually find this particle effect to look better on native 1080p than 1440p dlss quality because of what I mentioned before, it looks noticeably more blocky on dlss, it's also why the transparent window looks argueably nicer on native 1080p compared to dlss @1440p, and hell, I'd say it looks better than in the 4k dlss perf image because there it looks incredibly out of place, because it's trying to upscale an effect (the smudgyness of the window) that is dependent on the internal resolution, but still upscales it to 4k in the same way that the particles or ssr would be, so it looks jarring by comparison.
I guess the lines themselves are sharper, sure, but texture quality does not feel quite crystal 4k (which is a problem I've had in many games back when I ran dlss, textures never feeling quite right, now weather it's because of incorrect use of negative bias or just dlss, that's not my problem)
I'd also argue that Cyberpunk 2077 is not the best game to test this with, since that game has easily one of the worst TAA solutions I've seen any game have, spiderman might be a better go tbh, specially with SMAA
Anyway, I think I'll be sticking to 1080p thank you, low res, but not jarring (though the TAA is terrible, so I'll just not look at this game)
This was pointless
