    it used to be pretty universally 1440p from 4K in 1.0. BUt according to wolfenstein, it is 1080p, 1296p, and 1440p for 2.0.

    With DLSS 2.0 using it with 4K and performance preset the native resolution is 1080p:

    Dont know if performance is always "4X super resolution".

    With Balanced mode enabled the value Youngblood console shows for rs_forceFractionY and rs_forceFractionX is just shy of 0.58 which would mean 1252p.

    Thanks. It seems the patch is now available for download.

    Yeah tried it out just now, 4K-1440p DLSS now looks significantly sharper than 4K upscaled from 1440p, and I do mean significantly. It's an awesome improvement. It looks exactly like native 4K.

    Cool, the question is whether those same ratios hold at DSR factors too.

    On a 1080p monitor with DSR 4x and DLSS 2.0 performance does it render at 1080p, upscale to 4K using DLSS and then downsample to 1080p?

    Do we have performance data on this?

    DSR renders at higher resolution and downsamples. I'm not sure when the driver is downsampling though, is it some sort of post-process? Not sure which would be applied first (DSR or DLSS)

    Just don't go comparing the shots they posted and instead look at the originals.
    I've only looked one so far (the last pair, receptionist or something) and at least in that particular one there's obvious ringing artifacts and some really odd ones, like the row of darker dots in one of the hinges and high contrast "raster dots" on the posters alarm clock, or the incomprehensible "rules" text in one of the posters

    I'm not sure why they come to that conclusion. Looking at the first couple of their screenshots in 4k, the native is much better.

    Their screenshots left a lot to be desired. Definitely will need to wait for a better DLSS 2.0 review.

    Are you sure you didn't misread the labels? The placement of the labels between shots makes it harder to determine whether the label is referring to the shot above or below it. For every pair, the top shot seems to be with DLSS on and the bottom one DLSS off (native). For the first pair:

    Native: https://www.hardwaretimes.com/wp-co...Control-Screenshot-2020.03.25-19.28.28.30.png

    I think they learned a bit from AMD ... lots of people like a bit of oversharpening.

    Are we seeing the same thing? first pictures are DLSS on, and those are the better ones, the softer ones are DLSS Off/native. Far away text is very slightly distorted with DLSS on of course, but the overall sharpness of the image speaks for itself.

    According to NV there are no sharpening and this result is what NN outputs.

    That's not saying much, if you train it on super-sampled frames with a bit of sharpening the NN will sharpen. Or maybe they just add a bit too much LOD bias for my taste?

    Or maybe it's the game ... it's possible that because of non-linear colour operations super-sampled frames actually make the textures look aliased. Can't blame DLSS for that. Comparisons should add super-sampled/DSR frames as a groundtruth for comparison.

    Again, are you looking at the right labels? I have seen the originals of the ones you mentioned, the DLSS picture is definitely sharper and more defined than the native one.
