Show me any linux native application that can use it. Even catalyst doesn't support it under linux.- linux mantle support
Show me any real application which uses it on Linux.- OpenGL 4.4
I don't have R series. So for me it is also irrelevant.- for the R series true audio support (does someone know if this is planned / work in progress?)
This is SteamOS problem. Normal distros have full support of open source drivers.- official SteamOS support replacing catalyst!
It is already fast enough for most users.- a bit more optimization / performance
radeon-profile has some of these features.and a nice gui (extending radeonprofile) with:
- overclocking / fan control
- different game profiles
- 75 hz support (but I think thats up to mesa or the KDE monitor config tool)
- full color / video settings
The bottom line is that for me radeonsi is already much better than catalyst.
