GSync above monitor refresh rate?

post #1 of 11
Thread Starter 
Can someone give me a definitive answer as to what happens when your FPS exceeds your monitor refresh rate?

All I can find is conflicting information, some say that when you go above your monitor refresh rate then VSync is enabled instead...

And I have also read that with current drivers that GSync simply stops working above the refresh rate and doesn't turn on VSync.

I have a 144Hz 1440p acer predator and a pair of 1080ti's. I am wondering what my optimal GSync related settings would be. I am trying GSync enabled at the moment with a FPS cap of 144 in BF1.

When you have vsync enabled either in game or in nvidia settings, Gsync is "on" from 30-144fps. Below 30 you won't ever see with 1080ti, but the frames appears twice as long. At 144fps+ Gsync is "off" and vsync is "on." It's up to you whether you feel the added input lag or not, most people don't.

Specifically for bf1:
1) sli has major issues and you will most likely want to play with only a single 1080ti. Sli did work months ago for some users but it was broken with a patch.
2) use -GameTime.MaxVariableFps 142 in your game launch parameters, along with vsync enabled in nvidia settings (not the in game vsync.) Your fps will be limited to ~142fps with the least amount of input lag out of any combination.

What you have read is correct.

At defaults with the latest drivers, when the framerate goes over your refresh rate, Vsync isn't applied automatically so you'll see tearing. No idea why they decided to do this.

This is why I force global Vsync to enabled in NVCP.

So I should say that I just overclocked my monitor to 165Hz. I have BF1 capped at 144Hz now and G-SYNC enabled in NVCP. I am getting around 100FPS on ULTRA @ 1440P with GSYNC on and the FPS cap. Without G-SYNC I was getting more like 150fps.

Are you also saying that I need to enable V-SYNC? Why?

EDIT: I have set SLI Rendering mode for BF1 to single GPU and I am now getting the 144fps cap nearly all the time. G-SYNC is enabled and my monitor is 165Hz. I guess this means I am running G-SYNC fine now? Or do I need to enable Vertical Sync in NVCP as well? It is disabled in game.

You can change the command line to -GameTime.MaxVariableFps 163 and enable vsync in nvidia control panel and be good to go

Weird, I have no issues running BF1 with 2x 980s SLI enabled (95%+ usage), ultra settings, on 1440p Gsync monitor with no issues. Is it an issue with 1080tis only?

Why am I enabling vsync when I have GSync enabled?

From what I read, I should enable G Sync and cap my FPS below the refresh rate and job done. Another way to cap the fps is to enable vsync but that's not needed if I'm capping fps in game.

Quite true. I recommend vsync on within Nvidia Control Panel to never have to bother with it for other games.

Here is a great synopsis: https://www.blurbusters.com/gsync/gsync101-input-lag/

So it would appear then that G Sync when enabled will always be active upto the monitors refresh rate however will allow your FPS to exceed that refresh rate and when it does, G SYNC will turn off.

There are two ways of dealing with this:

1. Enable GSYNC and use FPS CAPS in games just under your refresh rate.

Or

2. Enable GSYNC and enable VSYNC in the NVCP since Vsync will hard cap your frames to your refresh rate across the board... However VSync will not be introducing input lag since upto the refresh rate it is actually G-SYNC in use, and you wont be able to pass the refresh rate.

Think ive got that down?
