I’ve been searching around the web for this, but I can’t seem to find any information other than a bunch of posts from the week after the launch of RDNA4.

Anyone know i Optiscaler is compatible with Linux and/or if there’s any word from Mesa/AMD on it?

In the comment section of a review by Tim from Hardware Unboxed I saw a person who managed to spoof their GPU on Linux to use FSR4 with RDNA3. Performance was very low (much lower than even native resolution).

So, it does look like it leverages hardware features introduced with RDNA4.
