TL:DW is AMD hasn't said that they DON'T block DLSS for AMD sponsored titles and refuses to say anything other than "no comment", while nVidia says they do not block for nVidia sponsored titles.
This leads us to the conclusion that AMD is blocking DLSS in AMD sponsored games unless AMD state otherwise.
I'm pretty much an AMD fanboy and this makes me real sad... :( This is something I've come to expect from nVidia in the past.
I'm a console player but I'm happy this is gaining traction. Exclusivity on graphical features on PC is the kind of BS we don't want on an open platform. I hope AMD revisits their dealings after this backlash.
