G-sync

Recommended Posts

Posted · Original PosterOP

I have a 144hz monitor with g-sync. I enable g-sync and set my frames to unlimited so I can push 300 to 400 FPS in game (fortnite). Does this mean that g-sync is still capping my frames at 144 or does it disable when my frames exceed 144. Or does it cap at 144 and I can feel more smoothness from the extra frames exceeding 144? 

Because I can tell a difference when I cap to 144 and it feels way smoother when I set it to unlimited. That’s why I’ve always stuck with unlimited..never witnessed any screen tearing or stuttering. Maybe it is there, but I’m just not noticing it.

you can disable Gsync altogether with uncapped frame rates and it will feel just as smooth. Adaptive sync tech in general doesn't work when you generate more frames than refresh rate.

Your screen is 144Hz.

 

When your game is running at below 144 FPS, G-Sync will lower the screens refresh rate to match your FPS in order to prevent tearing.

If your game is running above 144 FPS (In your case, 300 to 400) G-Sync will have no work to do and you will get screen tearing.

 

The very simple answer is that G-Sync prevents screen tearing only if your game is running at or below 144 FPS. It your FPS is above the refresh rate of your monitor G-Sync will do nothing.

 

Best to do is enabled V-Sync and G-Sync. That way your game will never run above your monitors refresh rate, and if it does dip below 144 FPS G-Sync will smooth out the image and prevent tearing.

 

G-Sync does not cap frames. However V-Sync in games can cap frames.

 

Best option is V-Sync on and G-Sync on.

 

And yeah, some people doesn't really notice screen tearing. But it's kind of one of those things if you start paying attention and know what to look for, you'll see it and get annoyed. It's kinda like a crooked picture on a wall, if you just glance at it and run around no one will notice unless you out-right stare at it.

 

I don't really see any screen tearing in games myself, unless I do some serious camera spinning just for the heck of it. But during normal gameplay? Never. But I still use V-Sync to cap my games at 60 just because I like playing at 60 FPS. And it prevents my GTX 1070 from sound like a vacum cleaner trying to take off.

Do not use VSync. When you have a G-SYNC panel, VSync is completely pointless.

well thats not true. v sync still has work to do. v sync should be activated with g sync in nvidia control panel and v sync off in games. you need to cap your refresh rate below your screen refresh rate by 2-3 fps and i recommend riva tuner. and u get smooth games with the least input lag possible.

As @charbel1011 mentioned. Those are best settings to have proper gsync and not experience any lag caused by v-sync if you do not cap frame rates. As for fps and refresh rate, if your monitor is 144hz having more than that makes zero difference, just more load on your system, as monitor cannot show higher. And if you have gsync on with v-sync on in global settings without capping frame rates, once game reaches 144hz and above v-sync will kick in causing input lag. :) Hope it clears it up!
