G Sync or G Sync + Vsync?

post #1 of 10
Thread Starter 
Do you all use G Sync by itself or in combination with Vsync? I've always used G Sync by itself but what happens when frame rates exceed the max refresh rate of the monitor? My monitor happens to be a 144hz monitor and many of my games often go well beyond 160fps (since getting a 1080 ti LOL) ... so what's going on in that situation? Is it better to run V sync at the same time as G sync so frame rates never exceed your monitors refresh rate?

thanks@!

joel

Experts seem to agree that if the framerate exceeds the refresh rate, then G-SYNC disengages and V-SYNC takes over if V-SYNC is enabled. It's generally felt that this is bad because V-SYNC reportedly has noticeably worse input lag, so it's recommended to cap your framerate at maybe 2-3 Hz below your refresh rate. The method of capping that's reported to be best is in-game capping, if it's an option in the game. If it's not, then of course the only other way is by using something like RivaTuner Statistics Server.

 

I am trying to use RivaTuner Statistics Server to cap my framerates for Portal 1, but I still see tearing that creates like a horizontal tear from left to right. It's not bad or even distracting at all, but I do notice it on occasion if I'm not really focused much on the game.

 

So far, that's the only game I've seen tearing in with RivaTuner Statistics Server capping. I don't have any games that allow me to cap in-game, but that's ok because those games don't get good enough performance for me to worry about anyway (maybe 100-120 FPS max).

 

I keep V-SYNC disabled in-game and in the NVIDIA Control Panel because if it's enabled at all in any way in the NVIDIA Control Panel, then Windows will be using it for its windows. This includes windowed mode gaming and borderless windowed mode.

 

Speaking of which, I have found that the best G-SYNC setting is the one that enables it for both full screen and windowed mode so that it is enabled for borderless windowed mode games too (particularly games made in Unity).

Run G-Sync with Fast Sync (this way if framerate exceeds monitor refresh rate, the excess frames get dropped). SEE: http://nvidia.custhelp.com/app/answers/detail/a_id/4161/~/if-i-have-a-g-sync-monitor,-should-i-enable-fast-sync-as-well%3F

Twocables: I haven't had much luck with most non in-game frame limiters .. rivatuner, Nvidia INspector, etc. ... it seems to introduce random stuttering on both accounts ... and even though I've traditionally only run G Sync by itself, I've still never noticed any tearing when playing over my monitors 144hz refresh rate ... I might not be as sensitive as you or others ...

bizplan: thanks for that reading information ... I'm going to try that this evening ... thumb.gif

Fast Sync is a subset of V-Sync in the Nvidia control panel, see:

I'm not saying I'm sensitive to it. I'm just saying that I can see it very easily in Portal 1 (it might just be Portal 1, I don't know), but it's not so bad that it's distracting.
