As far as I can see[1], when the game detects GL 4.3+, the engine tries
to load a different set of shaders from disk, but the game developers
have not enabled the right flag during building, so the shaders for
GL4.3+ are not actually distributed with the game, which results in a
failure to load the game. From my POV this is entirely the fault of the
game.
I can confirm that these ARK games fail to start with a 4.3+ context.
But from my point of view, I'm not really *sure* it's a game fault
because as you said in the related ticket, the game starts correctly
with AMDGPU-pro because it returns the right context. Maybe we should
just do the same?
That said, the bug contains a report from someone else that it works on
intel with GL4.3+.
That was me. The game is still early access and has been updated many
times since.
I never got to test that or look deeper into this, so
it could very well be that I overlooked something during this analysis.
It would be interesting to get a confirmation, but I don't have any
intel hw here.
Results from quick try on Ubuntu 16.04 with today's version of the game
(ARK: Survival Evolved)...
With (Ubuntu 16.04 default) Mesa 11.2, game starts to the game main
menu, but when one starts from that a single player campaign, it will
crash before the real game begins, after few minutes of loading (when
game RAM resident set size has grown to ~10 GB):

With latest Mesa (with or without the patch), game will just show a
small dialog with few garbage characters and exit. I have no idea what
it wants to complain about.
