They are a press outlet with a very strong financial relationship to Nvidia.
Do you have evidence that Nvidia work accounts for at least 10% of their revenues?
As for the real shills, reddit is already echoing with voices claiming AMD does not support their GPUs.
Yeah, and DF ain't one of them, it was bad choice from a very large Nvidia shills PR network.
Anyway, stuff like FSR4 requires expensive engineers time, and AMD needs to sell new hardware rather than x2 time for said engineers to make it work on old stuff they've stopped selling years ago.
Now I actually think they'll bring it at later date and they are just trying to make it work good on base PS5, but maybe not - either way one should not expect old product that did not support ML stuff well to suddenly gain new features that totally depend on it, that's just not reasonable.
