Actually, Valve has quite a strong hand in figuring out drivers for SteamOS, and they really only concentrate on Geforce and Catalyst drivers, and not any of the open-source stuff. AMD's drivers for Linux work well, it's just that their 3D performance with GCN has been atrocious for some time now. AMD's driver performance was much better on HD6000 and older series.

If you had to rename "csgo_linux" to "hl2_linux", you'd get a massive jump in framerates. AMD's profiles for games in CCC still need a lot of work when it comes to Linux support. This problem was highlighted by Phoronix, but AMD hasn't yet done anything about it.
When it comes to cards based on Tonga, Hawaii, and Fiji, AMD has a massive resource utilisation problem for these cards that they seemingly can't find a workaround for. Even with Vulcan coming into the mix next year, I don't think they'll be able to get things together properly without having a larger driver team for Catalyst on Linux.
