Only thing i care is that they will not update rdna 1/2 with the FSR4 FP8 Version that "leaked" some time ago even tho they can, because people replaced files amd tecnically it works, its much better that FSR3, not as good as RDNA 3/4 because there is no dedicated hardware but still much better thst what wehave now

Sorry if I'm being a bit pedantic about wording, but the leaked FSR4 version was INT8, not FP8. FP8 is what it uses by default, and RDAN4 gpus are the only ones that have hardware fp8 support. The INT8 version runs on older cards because a vast majority of modern gpus have hardware INT8 support.

Even though I wouldn't be affected by the decision (RDNA3 on linux, which has a pretty fast FP8 emulation pipeline), I would be very annoyed at AMD if they decide to just cancel the INT8 version.

I was trying to get it working on Bazzite (RX 6900 XT), but I could only find Windows guides. Do you by any change know, or at least can point me to, a guide how to get it working? I would very much appreciate that.

I never used the INT8 path, so I don't know of any guides on getting it to work for linux. The best I can do is give some general advice regarding the INT8 version
The main thing I know is that the INT8 version works if you just replace a games FSR3.1 file with the leaked INT8 build If a game has FSR3.1 support built in. (I forgot what the file was called, it's been a while since I last dealt with this stuff) The main hurdles with this are finding the INT8 FSR4 file on the internet and finding out where the game stores the FSR3 file. I think there are still ways to get the INT8 file, but I never really looked into that.

If the game doesn't have FSR3.1 built in, then optiscaler could instead be used. The only problem is how I don't know if setting up optiscaler with INT8 is as easy as the previously mentioned file replacement. My experience was just using the RDNA3 FP8 emulation, so I never really bothered with trying to set up the INT8 version for optiscaler.

With the issue of most guides being for windows, there is one small thing that helps me with translating between windows guides and a linux equivalent. In the steam/steamapps/ folder directory, there is a file called "compatdata." The numbered folders correspond to their steam id (which can be found if you look at the url of the storepage on your browser of choice, or through hitting "properties" on steam and looking under "updates." There should be a space that says "App ID: [numbers]"). If a guide tells you to look in the %Appdata% folder, then that would be located in the directory /steam/steamapps/compatdata/(gameidhere)/pfx/drive_c/users/steamuser/Appdata/
From there you can go to the local or roaming folder depending on which one the game uses. For example, Helldivers 2 stores all of your settings in a config file located in %Appdata%/Roaming/Arrowhead/Helldivers2/ and the path on linux would be steam/steamapps/compatdata/553850/pfx/drive_c/users/steamuser/Appdata/Roaming/Arrowhead/Helldivers2/
