While DLSS 2.0 may be technically superior in some situations, AMD’s counter for that is broader support and ease of integration. FSR works on lower-end products, even those from Nvidia, which is pretty neat.

I have to say I'm very positively surprised by the FSR "Ultra Quality" results. The graphics look almost as good as native.
computerbase:
Even if DLSS 2.0 is ahead of FSR 1.0 in terms of technology, it remains to be seen which upsampling technology will prevail. Because FSR has the undeniable advantage of being functional on all important GPUs - be it Radeon or GeForce (or in the future Intel), while DLSS only works on GeForce RTX graphics cards. And the less complex technology obviously also makes implementation easier for developers.
