AMD RDNA 2 And RDNA 3 GPUs Reportedly Suffer ~10% Performance Loss With FSR 4 INT8

https://wccftech.com/amd-rdna-2-and-rdna-3-gpus-reportedly-suffer-10-performance-loss-with-fsr-4-int8/

VS FSR3 that is, still gives more fps that native.

After the fatal Github error and all the tests that have ben done since, the only good option AMD has is ti officially support FSR4 on older cards, even if it makes so with an added disclaimer that to experience the best results of FSR4 you need an RDNA4 GPU. 

But of course, it's AMD, and they've chosen the wrong option many times in the past.

There are a couple Problems for AMD right now with this:

1. The image quality is, while a lot better than FSR 3.x, still quite a bit worse than with FSR4 on RDNA4 GPUs. Maybe AMD tries to fix this first before releasing the patch.
2. It doesn't work with all FSR4-enabled games, and in some, it actually comes with a performance regression, indicating that it needs more support before any official launch.
3. Since the performance drop for RDNA3 and RDNA2 is actually pretty much the same, there are many questions about if RDNA3 actually uses Int8 or it only being a workaround to get it running somewhat differently than on RDNA2.

In other words, while the prospects of releasing it right now seems good, evidence shows that it's simply not ready for the primetime just yet. So in my opinion, the best move AMD could do would be to acknowledge it and saying that it needs more work to make it truly work on the older GPUs and dispatch some work towards this end.
