To clarify, I know what DLSS is, but the question is legitimate.
And this sums up precisely why I just don't get the hype around DLSS. It's something that needs to be explicitly implemented by developers in order to use a bunch of transistors I've paid for, otherwise they're going unused. One could say I've actually wasted a chunk of my money if I don't play any of those 14 games listed above. I am literally seeing a drop in the performance level of my shiny Nvidia purchase if devs do not implement it. Conversely, you can't treat DLSS as "value add" if you've actually paid for the transistors, they're not a freebie.
And this is also why I refute the claim of "AMD needs a counter" because they already have. 2, in fact. FidelityFX requires dev implementation, but there is also the driver-level Radeon Image Sharpening. That works on every game. And both don't require dedicated hardware to do so.
