FSR has tons of aliasing and shimmering, this is just a basic upscaler with sharpening, barely any better than standard Resolution Scale setting, if at all, while DLSS not only resolves a lot of things better than native resolution, but also has the least amount of aliasing of any AA technology to date, maybe save for some instances of MSAA+SGSSAA in older games with less complexity, only the difference is that it can double the performance while doing that instead of cutting it in half. Sure it has some problems in motion, but that is hardly an argument in a world where almost all games are using blurry TAA as the only AA option and basically are one huge temporal artifact themselves. AMD really played a very cheap trick with FSR and it is sad to see the sheer amount of people buying that.
