Look, we've all made mistakes. One New Year's Eve, I accidentally drunk-texted a relative instead of an ex, and let me tell you, I'm still living that one down. AMD doesn't appear to be immune to the odd 'whoopsie daisy' either, as it appears it's accidentally released the source code for FSR 4 on GitHub before switching it to the regular SDK, and it's made for some interesting reading.
Videocardz managed to grab a screenshot of some of the file directories, which appears to show libraries for INT8 shaders, suggesting that it was originally designed for (or perhaps, will be supported in future by) older graphics cards. It's difficult to know for sure, but what we do know is that releasing the code was a mistake, as AMD has since replaced it with the normal SDK release.
