Like I said...you don't know what DLSS is, or how it works. It's not using "AI", that's just marketing bullshit. Apparently it works on some people
You can find tons of info on this (why I told you to search it up), but it uses rendering tables, inference sorting, and pattern recognition to quickly render scenes with other tricks that video formats have used for ages to render images at a higher resolution cheaply from the point of view of the GPU. You render a scene a dozen times once, then it regurgitates those renders from memory again if they are shown before ejected from cache on the card. It doesn't upsample, it does intelligently render anything new, and there is no additive anything. It seems you think it's magic, but it's just fast sorting memory tricks.
Why you think it makes games better is subjective, but it solely works to run games with the same details at a higher resolution. It doesn't improve rendered scenes whatsoever. It's literally the same thing as lowering your resolution and increasing texture compression (same affect on cached rendered scenes), since you bring it up. The effect on the user being a higher FPS at a higher resolution which you could achieve by just lowering your resolution. It absolutely does not make a game playable while otherwise unplayable by adding details and texture definition, as you seem to be claiming.
