GunShotNVIDIA has the most wise idea, obviously, like always. Do NOT concentrate on having your advanced reconstruction sampler, etc. working on your rivals GPUs if you care about best-in-class performance on YOUR GPUs that will force your rivals to compete (which XeSS is and it's 2nd best, very impressive just to be a few weeks-old) and have them jelly looking inferior in envy.

wolfAfter watching the Hardware Unboxed content on XeSS we can plainly also see why Nvidia won't let it run on competitor products, as since it not only runs worse but looks worse, but is called the same thing, it harms the name. It's really of little benefit to the consumer to open it up like XeSS with a slower generic codepath, there are already great open alternatives, so with that and dragging the name down for Nvidia, plus it being the class leading solution, it makes little sense. It's also now quite obvious how much of a difference further accelerating reconstruction can make, and come to think of it I've not heard much trash talk about tensor cores since then...
