Re: version string for OpenGL not correct?

I see.
Given that the game is recent and seems to be an AAA game, I'm pretty sure
it requires OpenGL core profile and not Compatibility (also called "Forward
Compatible").
So this is clearly and error from the game.

Hopefully Mesa has a mechanism to override the GL level it exposes.
You can experiment this with this command :
$ MESA_GL_VERSION_OVERRIDE=3.3FC glxinfo | grep "OpenGL version"

So try to launch Steam :
$ MESA_GL_VERSION_OVERRIDE=3.3FC steam
