    Other than that, I haven't tried it on wine since the reports on the net aren't too positive about the results.
    It's not about open vs closed, it's about nvidia's drivers are not compliant with OpenGL specs. So games developed on it are not compliant.

    According to Steam's Civ6 page:
    That's because they are fucking morons. Literally ALL people know nvidia's drivers are -NOT- compliant with OpenGL specs. And -EVERY- game developed on nvidia hardware is -NOT- compliant with OpenGL specs. You're better off running it in wine honetly.

    One could advertise any FreeSync monitor as tearfree and stutter free . But even FreeSync is relative, it do it only in ranges of this to that and is different from model to model:

    https://www.amd.com/en/products/freesync-monitors

    That G2460VQ6 model goes in range of 35-75, if fps rate goes bellow 35 it won't be synced of course.

    Question could be, does framerate goes below ranges for him when that stutter happen? Use GALLIUM_HUD to watch it. If he couldn't make a video, he could take a screenshot with hud enabled and if fps goes bellow then stutter is normal, etc...

    Also if he didn't use FreeSync just VSync then anything that goes below 75 framerate is also normal to stutter

    Is that big stutter or short stutter PC games have various setting usually, so user could found offender. They are not Playstation like games without settings - smoothered by creator a la movie and 30 or 60 fps by design

    This is the monitor http://us.aoc.com/en/gaming/products/g2460vq6

    edit: thanks for all suggestions but most likely I've already anything easily googlable. I suspect other people have similar issues but for various reasons won't notice, maybe people already have pretty lowbar expectations for linux gaming but thats just a guess.

    now I'm curious, how many of you noticed the cursor path issue?
    Now I'm convinced it has something to do with freesync, just look at AOC's website for that monitor, it advertises tearfree and stutterfree. It's probably something proprietary clashing with the OSS driver....

    OK, that's interesting (and not what I expected). Any suspicious log errors ?

    Are the "worse issues with old DC" (do you mean the pre-DC display code or early DC ?) related to stuttering as well ? Guessing no...
    Nothing suspicious in dmesg and xorg log.

    The bad issue with amdgpu.dc=0 is not waking up after sleeping for a long time. It doesn't happen with the default dc=1.

    The only time I ever saw tearfree not work was on a old 72hz monitor with a weird modeline. You might want to look into generating a custom modeline for the mode you use and see if that makes any difference.

    EDIT: I will say that AMD's drivers -do not- handle the modelines for TV's and other odd displays very well at all. For many displays you just have to make custom modelines for it.
