Can this program be used (or potentially) as a form of antialiasing?
So, basically the question.

I'm not that interested in the frame generation aspect but i would love to know if it's a posibility to implement some sort of antialiasing technique. Kinda like TAA or i dunno DLAA for games that don't have good AA options.

Nier Automata, for example, has SMAA (which sucks, makes the bushes really noisy) and MSAA which looks amazing but it's incredibly taxing on the GPU.

Thanks

I've wondered about this as well. Though i would very much dislike it if it were built-in and it couldn't be disabled. Probably to the point of making it useless to me in most situations. Though it may be possible to add it as a post-process.

Configurability of the TAA would be nice as well, as the effective use of TAA is highly dependent on the situation, and tuning it to be a catch-all solution would most likely make it veeery blurry.

i wish it could.

No, it can uspcale from 1080 to 1440p with less blur. but no Antialiasing.

SSAA will forever be the best form of anti-aliasing in terms of quality, and probably also forever be the worst form of anti-aliasing in terms of performance.

When you consider that all these upscaling methods use the same base (Correct me if I'm wrong), in that the image is taken at a lower resolution and stretched out to fit your current resolution, and the method of upscaling being improving the quality of the "stretch", it is already "anti-aliased", except that instead of only the edges (Except for SSAA which is the only true technique (again, correct me if I'm wrong) that practically "AA's" everything), it does the entire screen.

If the above is true, which in most cases it is or should be (it's oversimplified though) then SSAA is the direct inverse of upscaling, with the exception that the SSAA technique doesn't need any "postprocessing" after it's been downscaled.

Since SSAA works this way, it can be applied to any game that supports true 3d acceleration. So, say, about mid 90's and on. (i.e. very old games that only support Software rendering cannot benefit from this feature if I'm not mistaken, these can have their own scalers in as you can see in for example, the dosbox documents.)

Therefore, you can find SSAA in the settings for NVidia's control panel (Named DSR, pick a high legacy option if you have a very powerful setup compared to the game you want to play, or the DLAA options there (just like you specifically mentioned...))

For AMD it's similar, but since I haven't used those drivers in ages, I can't tell you what exactly it's called, but it should be very straightforward.

yeah same thing supersampling anti-aliasing, i haven't dived into how effective it is tho.

well if you take sharpening as AA, this could be it.

That would have an absolutely inverse effect..

yeah, thats what i dont like about TAA
