Is this normal behavior for gsync?

[Fristelm]

Hey so If I have gsync on and vsync off in the nvcp I get screen tearing but when I turn on vsync in the nvcp the tearing stops. and my fps was always under 144 and above 30. I have the aoc g2590fx. Is that normal behavior?

[Jurrunio]

that's not normal, but maybe the frame rate spikes are very short so while it reports fps at below 144, it does shoot through it.

What would you recommend I do for me to fix it? And I used RTSS to cap my fps to 141 so it could not have went over.

Whether or not this is expected depends on if your fps kept inside the g-sync window or not, have it ever gone past 144fps when it teared?

V-Sync will lock your fps to the refresh rate and sync it to stop tearing entirely, what g-sync does is try to match the monitor refresh rate to your fps so v-sync will work perfectly all the time, that is why everything gets smooth and stays within the g-sync range, when you turn v-sync off g-sync still work but if you have like 165fps instead you're outside g-sync window and have no more frame sync causing the screen tearing.

 

So to validate your issue we just need to experiment with that, if you want all the fps you can get without tearing you can try nvidia's fast sync which is enable at the driver which works by letting card render even more than the refresh rate so it can use the latest fames always for whatever your native refresh rate is.

framerate cappers are pointless in your case since they won't help you solutionate screen tearing because G-Sync can only match refresh rate not synchronize your frame to the monitor.

check if the game provides a built in frame rate cap other than Vsync

It has gone past 144 and teared thats why I capped it at 141

Thanks for the replies do you guys think that it is defective?

It's not, you should just use V-Sync+G-Sync when you don't want screen tearing and if you ever go play cs:go where you need "the edge" use Fast Sync alone, it will help with less tearing while keeping framerate uncapped.

Will this cause me to have vsync level input lag though? because when I enable vsync, it goes away.... This is my first gsync monitor so I wanted to know if this behavior is normal.

Yes it is normal, whenever you have more fps than your refresh rate you'll be susceptible to tearing, the way around it is to use fast sync like I told you.

 

G-Sync helps when you want to play eye candy games with high settings that will cause you to have fps fluctuation under the refresh rate, it's not a technology for e-sports where you have hundreds of fps.

 

V-Sync Double Buffered at 144fps has considerably low input lag addition, it depends on the monitor exactly and all the total input delay you'll experience... you should try for yourself to see if you can feel it or not.

 

One way or another there is no perfect all around solution you need to adapt and use the technologies you have available depending on what you're after.

But my fps was not above 144 it was around 140 because I capped it there.... And there was tearing in my games. When I enabled vsync through nvcp it went away.

Yes it was tearing because you were using a frame capper and it does not synchronize your frames to the display like V-Sync does, it merely puts the "cap" in there and G-Sync works it's finest WITH V-Sync since G-Sync will match refresh rate to your fps and then V-Sync synchronizes it.

 

With a framerate capper G-Sync should still work and match the refresh rate to your fps but there is no synchronizing going on.

So I am not getting vsync level input lag when I use them together correct? and are you sure this is normal behavior for gsync? Does this happen to you or other people with similar problems? Sorry if im being repetitive i have talked to so many people lol.

There will always be a bit of more input lag using V-Sync than if you leave it uncapped, framerate cappers also add input lag to a degree though, this is why I am insisting to exhaustion that if you want to play an e-sports game with all the fps you can get, going above your refresh rate, you should use Fast Sync which is available on nVidia drivers:

This is not a problem, this is how the technology works, G-Sync works by matching your refresh rate to your fps, this is all it does technically speaking but it only works on it's 'window' which is 30hz - 144hz, whenever your fps gets off this window G-Sync is not working.

 

If you play a game that cannot give you more fps than your refresh rate use V-Sync + G-Sync for the most smooth experience, if you play a competitive high pace game that can give you more fps than your refresh rate use Fast Sync, this is the bottom line... in no instance a framerate capper is going to be of any use to you.
