[Linux] OpenGL version 3.1 is required error

Hello,

When i try to start the game with optirun the game doesn't start and in the log i get the following:

Error: OpenGL version 3.1 is required

And when i try to start the game with my intel gpu i get this:

Error: OpenGL version 3.1 is required
Error: Couldn't initialize the render device.

I'm using Arch Linux (64 bit) with Openbox WM and no DE and all the drivers and the kernel are up to date.

Here is the output of glxinfo | grep -i opengl
Where could the problem be?

*(Edited post) I just saw on steam system information that steam currently is using OpenGL Version: 3.0
I will try to fix that now.

Thanks,
thechiprel.
