Scanline sync

So here is an update of what I did in the meantime: Following your suggestion I get a displayed FPS in the game of 225 average (MSI-A display during game and statistic graph after quitting game). I would like to have 30 average with Vsynch technically ON (also if disabled in the game). Maybe this is not possible because I don't understand well the technology, but if your recommendation is right I should see 30 in the MSI statistics for FPS with a 60Hz monitor, or not?

My exact settings are:
LCD Monitor plugged to gaming laptop with HDMI, Nvidia Panel says at native resolution 1920x1080 @ 60Hz (seems to be max. Hz, I cannot set any higher Hz resolution).
In-game Resolution: 1920x1080 @60Hz
In-game: Vsynch=OFF
RivaTuner Framerate Limit=0
RivaTuner Scanline sync x/2=0

What's wrong?

Thanks,

@XenonS
Use -50 for scanline sync. If there's tearing, try -80, -100, etc. This will control the tear line.

0 disables scanline sync.

 

For whatever reason, it works much better with DXVK than with native D3D11 in Witcher 3 and HotS. I can't get it to be stable with D3D11 without FastSync, but that increases lag. With DXVK (and prerender limit 1 set up in its config), it remains completely stable until frame time > refresh rate (but then instantly syncs perfectly again for the next frame times < refresh rate).

 

Does this work for openGL?
I trying to set this up, but nothing works;

Game secenario:
QLQuake with reshade rtgi
5120x2880@ 60hz (mst, multi stream, essentialy two screens)
Framerate is 45 fps, 99% GPU load. with vsync on, it plummets to 30, with off I get tearing.

I have set a fps cap globally at 59.9 and tried -10, -20, or 2900 etc, but I keep getting tearllines.
Whill read this topic again to get it, butI am lost here...Doesn't it work when framerate is below refreshrate?

 

It doesn't, you need framerate higher than your refresh rate to get controllable tearline (or switch to Scanline Sync 2/x where you'll get half of your refresh rate - 30 fps).

 

^ Thanks, gonna check this out.

 

Yep working now
