The math just doesn't add up any other way. Sorry!
Are you and Jay competing for the Nobel prize to see who can repeat the same thing over and over again?
We already know 4k DLSS is 1440p upscaled. The question is if DLSS is doing enough a good job to warrant its use.
For Metro Exodus, YES.
For Battlefield 5, NO.
Metro Exodus gives a good, clear representation of the benefits of DLSS. It's quite funny reading the doomsday argument about blurring, artifacts, etc.. when I'm playing the game right now with everything Ultra including RTX and DLSS looks picture perfect as can be. I'd say it's about 90% equivalent to the native 4k image, with none of the aliasing artifacts.
Don't take my word for it though. There are other 2070/2080/2080Ti owners here. DLSS also works great at 1440p according to acroig since that's his native resolution.
