If I am buying top of the line GPU just to use upscalers,I am the biggest fool of all. Upscalers should be used to extend the life of older GPUs, not an excuse to poorly optimize the games. Man, what an ass backward industry is AAA games industry han become.
But DLSS is making devs lazy. I remember playing Spider-Man 2 on my RTX 3070 on High, Raytracing off and dlss both on and off. It looked noticeably worse than Spider-Man 2014 on base PS4. Maybe it is just one game, but I was really not impressed that a 2 year old game looked worse than 10 year old game.
