Re: GeForce GTX 1070, screen tearing w/ Nvidia

Have you got gnome, right? Or just a simple window manager.

@Sauko, https://bbs.archlinux.org/viewtopic.php … 7#p1903527

@AdvancedGans25
Tearing happens when the scanout buffer isn't updated (or not updated fast enough) during the vblank interval. Originally the time when a CRT had to re-adjust the emitter, on an LCD it's just a randomly brief time that the monitor waits between two frames.
Reason #1: The update isn't (properly) aligned to the vblank signal of the monitor (unsynced updates)
Reason #2: The vblank signal of the monitor happens at the wrong time (can happen with adapter driven signal delay - if the output is on an internal adapter, eg. DP => DVI and that hasn't been accounted for by the board vendor, you're screwed)
Reason #3: The update takes too™ long (can happen w/ reduced blanking modelines or if the monitor is just too™ slow to leave a reasonable update interval)

You could try to switch to a smaller mode (1440x900) and see whether the issue remains.
Did you try manipulating the two other parameters for mpv? Do they have *any* impact?

Well I had the same issues with other linux distributions, now I have got kde, wich has an compositor's option to enable vsync, now works perfect. If you dont want kde plasma, try to install a compositer manager, or something like that.
