basic system information
And probably a similar problem described in the steam community:
The game requests a 4.1 compatibility profile which is unsupported by Mesa and it crashes because it doesn't check the return value of glXCreateContextAttribsARB.
I'm investigating in order to know if it's possible to add a driconf option, but it looks like the game really needs some unsupported features.
Okay, the game uses ARB_texture_buffer_object which is only exposed with a core profile for some reasons. I'm able to run the game with some hacky changes but it fails to render correctly at some point.
Unfortunately, I don't think we can do anything for it because compat >= 3.1 is not supported for now (and probably won't be in the near future).
Anyways, the game should not crash when the returned context is NULL.
That doesn't sound to bad, does it?
At least it looks like the problem could be isolated.
Thanks and I'm happily trying fixes as long they're not exhausting my capabilities.
