G-Sync Issues

[makadee]

Can someone please help me on this. 

 

Basically what I have noticed is on my Alienware 34 Monitor AW3418DW I have noticed the G-Sync maybe is not working properly.

 

For example I will go into a game like Insurgency Sandstorm and with Vsync off I noticed a bit of screen tearing and just not as smooth. 

 

When i turn on vsync this issue goes away.....

 

I have G-Sync enabled in the nvidia control panel, and I am able to run the game at my resolution at above 100FPS.

 

Can someone tell me what I am doing wrong here or what it could be? Could it be that my monitor needs to be update or something?

G-Sync only operates when your framerate is lower than your monitor's refresh rate.

So basically if I am above 120FPS i should always have v-sync turned on?

 

Also I noticed this: I did the Nvidia test for g-sync vs v-sync vs nothing. I noticed that vsync and gsync at 40FPS looks the same like literally identical. But when I turn them both off i noticed a big different in screen tearing at 40fps.

 

So I am confused about if the G-sync and V-sync and why they are the exact same? Isnt G-sync supposed to be better?

V-Sync limits your fps to the refresh rate of your monitor. You will still experience screen tearing with just V-Sync because your monitor refresh rate and game FPS will not always be aligned.

 

G-Sync will synchronize the refresh rate of your monitor with the FPS of your game. G-Sync cannot operate if your FPS exceeds your monitors refresh rate because the monitor cannot keep up.

 

Most modern games have the ability to limit your FPS. I have done this in CSGO by limiting my FPS to 100 FPS because I know my 144 monitor with G-Sync can synchronize easily and I cannot see any difference between 100 FPS and 400 FPS (except screen tearing past 144). I have done the same with World of Warcraft, limiting my FPS to 100.

Yes

Both eliminate tearing, but V-Sync can cause stutter in some situations. G-Sync makes low framerates smoother.

When you use G-Sync, the effect of the V-Sync setting changes. If your framerate is below your monitor's refresh rate, G-Sync is used. If you pass above your monitor's refresh rate, G-Sync no longer operates. In that situation, the behavior depends on the V-Sync setting. If you have the V-Sync setting turned on, then it switches to V-Sync to continue preventing tearing. If you have the V-Sync setting turned off, then it doesn't switch to anything, and you may get tearing.
