    If it crashes it does not mean the driver is strict. It means the developers never thought that would happen so they didn't properly treat that case. Being strict implies you actually treat that case by returning an error.

    That is no longer the case. It was somewhat the case on Windows before steam appeared where updating random games was a hassle and it was easier to just update the driver every week. Steam on the other hand solves this problem so bugs should be fixed in the actual game not worked around in all possible drivers.
    There is also the issue with abandoned games. There, indeed, new drivers need to keep bug for bug compatibility with older ones.

    I was surprised by the fact that the models in the screenshot show no real-time shadows on the ground. Is that really correct? I never thought I'd see a game in 2016 where the characters seem to float in mid air. I thought this was a rendering error in the Gallium test, but if it's the same on Catalyst I guess this is really the way it's supposed to be...

    Plus another copy installed with each game in case the version in the drivers is different from what the game is expecting

    Well, my personal opinion is that undefined behavior should cause the game to stop and drop to a terminal emulator with debug info. No fucking silent CTD, that's some bullshit that should never happen. At least give me something I can copy and paste into a bug report.

    EDIT: I hate to say it like this, but I'm learning that it is true, all these new linux ports are only doing one thing. They are proving how bad game companies try to screw you. I read an blog post yesterday from an nVidia employee where he essentially said that if nVidia's driver didn't deal with undefined behavior on a game by game basis then linux gaming, in his opinion, would simply not be possible.

    Maybe that's true. Maybe native ports are not the ultimate answer.... They are proving beyond any doubt that they aren't doing it right.... Gallium Nine is performing better than a lot the native ports right now. Perhaps game companies should be using gallium and wine like a wrapper. I think it makes better sense. I don't think there is anything that would prevent them from distributing the wrapper for their games.

    Well, as you said : undefined behaviour. The spec doesn't say what to do. Crashing is one way, validating the input and ignoring wrong input is the other.
    ... another way would be to send the stacktrace to developers via e-mail, if the person playing the game agrees to do so by confirming a popup window.

    Clarification: The OpenGL driver should be sending the e-mail.

    Can't be, I mean everyone was saying that Feral and NVIDIA are in cahoots to make the game playable only on NVIDIA hardware.
