Its kinda funny and strange.
0.0 Screen percentage does actually make no sense at all as this would mean that 0 pixels would be rendered and therefor the display should be black.
I dont know but maybe 1.0 is actually in the realm of upscaling and 0.5 is actual full 1080p?
i guess this game has also had no dlss support as of now and maybe never will as i dont know how nvidia things about officially supporting beastiatlity themed porn games... ;D
DLSS would be massivly improve upscaling performance and quality.
Since this is a feature nvidia is training the underlying ai themself for now no dev can do this without them. So no DLSS without nvidia being on board with porn. Sniff
Back to render size so 0.0 maybe something like just under or being around 320 or so was the underlying res. #
From 0.2 this is looking better than some supposedly hd stuff from some cheaper porn site so this maybe be 640 x 480 and so on.
From what i remember form fiddling around in the ue4 editor 0.5 ingame looks to good to be the equivalent of the original setting in the editor..
But it has been a while and if that is indeed now the 0.5 value in combination with middle aa as low aa gives me artifacts, its insane how good this feature has become. But im still wondering if not upscaling may not be applied to this setting aswell and anything from .5 up could be also rendering higher than orig setting.
It certainly does look as good to me.
