Running steam on Ubuntu 1404, core i3, 6 GB, Acer Aspire M5-418, Intel HD 4000 graphics. When I want to start the game, the message: "fatal error: SDL_GL_CreateContext failed: could not create GL context" appears. What do I do now????! Thanks for the help!!!!
Same problem on Fedora 20 on both Intel HD 3000 and AMD Radeon 6750m (open source driver). I bought this game several months ago and until now it never ran on my system and I'm starting to think it never will. I totally regret buying this game.
Same problem here on Ubuntu 14.04. CPU: Intel® Core™ i5-4570 CPU @ 3.20GHz × 4 Graphics: Intel® Haswell Desktop RAM: 8GB OS: Ubuntu 14.04 Graphics Driver: Latest Intel graphics driver for Ubuntu 14.04
Same problem also. Tested with nvidia driver 331.38 from nvidia-331 and nvidia-331-updates. Ubuntu 14.04 i7 3770k, GTX 680
I'm find other guy on Nvidia with same issue and Ubuntu 14.04. He had same problem with 331.38 and bypass them with downgrading to 304.117. Can you please check it and post here about results?
I doubt Nouveau will able to handle PA even if game will support open source drivers. So you better use proprietary drivers if you want to play it on Nvidia.
I've got the same problem, with Gentoo, Core i5, HD 4600. Any hope to run that game? Edit: I was running 66503, I've just seen a new version : 66567. I'll try.
Nope until devs make it use OpenGL 3.2 core profile. At moment game need 3.2 compatibility profile which Mesa doesn't support.
"yet" isn't really the correct work - the game WAS compatible with open source drivers until some time age, so this is actually a regression. On a more important note: MESA seems to support GL3.2 completely: http://cgit.freedesktop.org/mesa/mesa/tree/docs/GL3.txt Or am I missing something?
Nope. I suppose Linux-specific GL code didn't changed much since Alpha released. Only reason why earlier versions of game worked on open source drivers somehow it's because game used GL 2.1 with few 3.0 features. Within development process game start using more advanced features, but it's still was possible to make shaders compatible with Mesa and this why I did. Unfortunately outdated GL hurt Mac version a lot because it's don't support compatibility profiles too and by default it's only have 2.1 (while Mesa have 3.0) so Uber decide to switch everything to 3.2 core profile on Mac: https://forums.uberent.com/threads/a-question-for-our-os-x-users.56431/ Once this was done game was no longer work with Mesa because Linux version still using old stuff. Even now it's still possible to disable a lot of shaders/effects/etc and run the game, but there is no point in doing so. Yes, you missing this:
So basically, the issue is that OS X has old versions of OpenGL, and Mesa has already gotten rid of the deprecated features?
No. First of all compatibility profile it's not just "deprecated features", but part of official GL specification. Intel devs (they handle most of Mesa core development) decide to not implement compatibility because it's too complicated and very few apps need it. As far as I understand not all of the GL code shared between platforms, so Mac version already using core profile for a while and since it's implemented game isn't compatible with FOSS drivers on Linux because Linux code wasn't adopted for code profile.
