Depends on the hardware requirements of FSR4.
FSR1-2-3 doesn't require the use of specialized cores like Tensor cores, which is why it worked on pretty much everything as it could be computed on the shaders, it was just a relatively simple algorithm.

RDNA3 can perform "Tensor" operations (Which is mostly just Matrix Ops leveraging INT4, INT8, BF16, FP16 for inference) but it lacks the dedicated hardware for it...

And this is where RDNA4 could offer some significant deviation... Which is set to offer FP8 operations, where RDNA3 will likely need to fall back to BF16... And that is likely what broke the camels back in regards to FSR4 support.

It sucks, but we will need to see if they are going to roll FSR4 into GPUOpen, there people will get it to work on other GPU's that do not support FP8 operations or perhaps someone will make a fallback to BFloat16 operations for older hardware.

There is a 3rd alternative... And that's to make a Radeon "tensor" accelerator as a separate add-in card for A.I upscaling and inference that will work with everything... But I would rather see the return of Physics than more A.I stuff.

Again I get the technical aspect about it, but at the same time it itself is a form of "demand" from AMD, and it is one they simply cannot produce a meaningful benefit for the consumer to go "yes, this makes sense, I will gladly fork over for your product", because so far that hasn't really been happening in spades, to gain them back a ton of market share. 

If anything this is them playing by the same book as Nvidia, but again, Nvidia has all that and more, so their demand for what it is to be what it is, makes sense.

I too would love to see the return of proper physics and improvements to in-game AI, instead of all the current focus on slightly fancy shadows, some lighting and smoke (none of which we can really interact with in a meaningful/impactful sense anyway). Nvidia recently dropping PhysX support has just made old game support with their latest cards look so bad.
