All I get from that Tom Warren tweet is that he doesn't understand how business works. While I'm bummed that DLSS wile likely be absent from Starfield, this is still a big marketing deal for AMD. And it ignores nVidia's history of absolutely tanking performance on nVidia sponsored titles if they were run on AMD hardware, often involving overuse of tessellation. AMD owners deserve optimization and preference just like nVidia owners do, and not only is it premature to judge the upscaling and vendor preferenced technologies, many of these issues will likely be circumvented by mods on PC. And that's what we are talking about here, because it isn't like the console versions are using DLSS.
For Microsoft/Bethesda/AMD sake, I hope Starfield PC performance is solid and not hamstrung to a 30fps target.
