AMD have finally released FidelityFX SDK 2.0, which includes support for FidelityFX Super Resolution 4 (FSR 4), so now all developers can use it.

Offering an easy way for developers to upgrade, it provides some pretty big improvements to image quality with their new Machine Learning based algorithm. It improves temporal stability, better preserve detail, and reduce ghosting and in many cases the difference is very noticeable.

As for the upgrade path AMD said:

This new release of AMD FSR 4 continues to use the FidelityFX API introduced in FSR 3.1, providing an easy update path for developers. New features are exposed using the extensibility of the FidelityFX API. AMD FSR 4 is available as prebuilt, signed DLLs as part of FidelityFX SDK 2.0 official releases to ensure stability and upgradability of DLLs, if allowed by individual game releases.

AMD FidelityFX SDK is open source available under the MIT license. You can find it on GitHub and their announcement for info.

at this stage no one cares, because FSR4 is AMD only and ONLY for new AMD chips technology.
I have most expensive and powerful to date GPU from AMD, and I cant use it...
