crash at startup - SteamOS

[loadrunner]

I don't know what the problem is, but it's not that.
I saw that (that it detects 3.2) and I also saw other topics here in which people claim SOMA detects 3.2 even if their system supports 3.3+. (people also with nvidia GPUs, I think .. ?)
The 367.27 nvidia driver, which is preinstalled with SteamOS 2 (stable) is pretty new (2016.6.13) and it supports OpenGL 4.5. (also glxinfo reports OpenGL 4.5)
I don't want to manually install a different/newer version because SteamOS doesn't recommend that and it might break future updates.

But regardless of that, shouldn't SOMA run on a stock SteamOS?
On Steam it claims it does work with SteamOS and it should.
I bought it because of that.

I will do some more digging and let you know if I find anything, but please don't dismiss this so quickly.
