Vsync is properly supported and should work fine, although it's not the first time I hear Nvidia users having issues with it (usually the other way around though). Can you try running the game from an X.org session rather than Wayland?
Also, do the FPS change when enabling Vsync? You can use export DXVK_HUD=fps to display the current frame rate.
It's not Wayland. Compton is an external compositor for Xorg. So if you're running a WM without a compositor or with a bad one (hi xfwm4), you run compton in addition and get a lot of configurability and some nice, subtle effects.
That said, OP, why did you mention compton? Have you tried running without it, or with different vsync options for compton?
Ah, must have mixed up Compton with Weston, sorry.
But yeah, compositors can very well cause vsync-related issues if not configured properly, that's worth checking.
go to nvidia-settings and under Display Configurations choose Advanced and enable ForceCompositionPipline for you monitor, that will fix the tearing. no need for vsync, which causes input lag.
You can also save this to your Xorg configuration so it will be enabled on every reboot.
that issue shouldn't even be here.
@xpander69 stop recommending that, it usually makes performance like 30% worse
what? what DE? i have ran several test with it on and off, performance is always about same, +/- 1-2%
@doitsujin you can close this issue. I changed compositor and the tearing disappeared, so it's probably a Compton related issue in my case. Thanks for your answer!

Software information
Seen in Witcher 3, but I have no idea if it is related to that game or a widespread issue at this stage.
System information
Vsync on/off does not seem to change the rendering at all, which always shows some slight tearing especially visible in rapidly moving scenes. I do not have tearing problems with other games on the same distro/hardware, so wondering if it's just because Vsync is not properly supported yet or not.
