Here Is What Happens When Trying To Use Non-NVIDIA Drivers To Play XCOM 2 On Linux

The issue was found: LC_ALL was set to French language, which uses comma as decimal separator. LC_ALL should be unset.

Just something related: I have had problems with uncommon language settings when running Steam games in the past. I solved it by adding "export LANG=en_US.utf8" to the script from which I am usually starting steam.sh.

Note: That being said, it would be better if Steam and Steam games worked with any valid LC_* and LANG settings.

I have further news: it is now working on my "non-working" machine using a brand new user account! So that means the issue is not system wide, but related to some user specific setting. I am quite puzzled, because I had initally reinstalled Steam entirely on my non-working user account and it did not solve the issue. So that means the problem is with another file. It is also a relief, because diagnosing it should be a lot simpler. I will let other users having the same issue know, and see if they see the same thing, and if they can help figure out the cause.

That looks like Chromium debug output, probably just from an embedded webview. Also explains why it is GLES, Chromium uses GLES (or WebGL), to transfer OpenGL commands between their processes.

Yes, but I do not see these messages when running Alien Isolation for instance.
These errors seem unrelated, but could they interfere with a game?

I (and 4 other users on Steam) have the same issue with Nvidia drivers: it does not crash, but main menu and maps are black with some drawing artifacts. Case is discussed here: http://steamcommunity.com/app/268500...6292761093493/

The GL debug output has these context errors:

Feral says they have not been able to reproduce yet.
The strange thing is that Xpander69 has almost the same system than me (Archlinux 64, GTX970) and it works for him with 361.18 drivers. I also tried 352.63, same issue. Other games like Alien Isolation, Civ V and Shadow of Mordor work fine!

And once again every driver except one struggles as a new title is coming to Linux. These driver vendors really need to get their act together.

Crash too with the proprietary NVIDIA v361 980 :'-(

To be honest, even the 'officially supported' Nvidia implementation is pretty sub-par. Due to a combination of Nvidia being intransigent in their opinions about how RandR 1.2 should be used, and Feral's rushed implementation, I can't even change resolution, no matter what I do - the game hard-resets the resolution to whatever is reported via RandR 1.2, and Nvidia only returns native EDID-reported resolutions (they refuse to provide scaled metamodes via RandR 1.2, even though every other driver does it, because reasons). Even if I change the desktop resolution, I end up seeing a fraction of the game viewport, which will only (and always, it overwrites any changes made to the config by hand) render at the native 4k of my panel, and at 4k the game is completely unplayable from a performance perspective on a 970m.

Really don't know what to do here, because I'd like not to miss my refund window if it's not going to be fixed, but I really would like to play this, if it was playable.

I think that some people around here don't want to actually see any test results Michael. I think they just want a wall of text rant about how AMD GOOD and everyone else BAD.

There are plenty of other websites out there that cater to their needs.

What are you talking about? The Radeon driver was where most of the tests happened.

I'm making this real easy for you two: On the first page of the article Michael wrote this:

Mesa 11.2-devel with LLVM 3.9 (via the Padoka PPA) and the Linux 4.5-rc2 kernel (with AMDGPU PowerPlay enabled) was used for this testing... I don't plan on doing any older Mesa tests, since Mesa Git offers the best OpenGL 4 extension coverage as well as the best performance

Which is, for obvious reason, untrue. It also means AMDGPU was used for the entire test (unless I'm missing something here).
