Driver settings for GSync

So much conflicting information out there!

Currently I've got the driver set to default : Let 3D Application Decide.

The problem is games are running over 144 fps and thus creating tearing (kinda defeats the purpose of G-Sync no?) For example Diablo 3.

So I enable V-Sync in game, but I'm reading I shouldn't do that? Some are saying to manage 3D settings via Nvidia Control Panel, so do I enable VSync in there and Triple Buffering? Will that render any other graphics settings I change ingame useless?

So confused
 
If you enabled gsync in the section specific to gsync then the vsync option in 3D settings changes how it works - with it on the game works with gsync on always if you select off it works as gsync on when you are rendering below your refresh rate but disables gsync while you can render at framerates above your refresh rate.

Don't enable vsync ingame (though in most cases once gsync is enabled it won't do anything).
 
Ok so thus far I've found Diablo 3 and WoW worse with v-sync disabled ingame.

I've currently left driver to "let 3d application decide".

Question I have is if I DO enable vsync ingame, does it behave the same as the driver version? Meaning gsync is still working fine but vsync kicks in at 144?

I don't really see it worth while enabling vsync via driver as for FPS that would itroduce input lag over 144 wouldnt it?
 
LEAVE VSYNC ENABLED INGAME.

When the driver is set to use GSYNC it will override/enhance the game setting and use GSYNC technology. You are over thinking this. Enable GSYNC. Use VSYNC ingame. Forget about it and play.

Edit: Do you have it set up like this guide? http://www.tomshardware.com/reviews/rog-swift-pg278q-g-sync-monitor,3897-2.html

That guide is now out-dated.

-Open nVidia control panel.

-Find Display->Set up G_SYNC in the left pane.

-Tick "Enable G-SYNC" with the "Enable G-SYNC for full screen mode." option (the window mode option has some caveats that need to be understood before using it)

Under 3D Settings->Manage 3D settings the "Vertical sync" option will now be limited to On or Off:

On = traditional G-SYNC behaviour - FPS will be capped at the refresh rate, no tearing should be present.

Off = uncapped rendering rate - when your FPS exceeds your monitor refresh rate it will render as fast as possible but tearing will occur, when your frame rate drops to or below your refresh rate tradtional G-SYNC behaviour kicks in and you won't get tearing. (this has been requested by some "pro-gamers" who wouldn't normally use VSync as a nicer way to handle lower framerate situations while still benefiting from the responsiveness of being able to render extremely fast).

To my knowledge the triple buffer option does nothing in G-SYNC mode and likewise selecting VSync ingame shouldn't do anything in G-SYNC mode - in some edge cases where games have some kind of implementation of their own it might cause compatibility issues.

erm, all the guides for Gsync, including the one written by nvidia, say to turn off vsync in game, as it can prevent gsync from working

there are options in NVCP for having Gsync + Vsync or Gsync - Vsync (if not using vsync you can then use a frame limiter either by game config or something like afterburner)
 
Oh see I just turn Gsync on and limited my frame to 135 with MSI.

Clearly that isn't the way.

Oops
 
See when I do it : GSYNC ENABLED / VSYNC ENABLED VIA GLOBAL SEttinGS

Some games still exceed 144fps, namely WoW and D3. They seem to ignore the drivers vsync value pretty much. Likewise if I was to disable vsync from the driver and enable it from the game, it will stick to 144.

Hypothetically, if I chose to run with vysnc disabled via driver and enable vsync ingame, is that any different to enabling vsync globally via driver settings? Will it affect Gsync?

Make sure the game is running fullscreen and not borderless window or windowed modes G-SYNC doesn't work in games that don't use proper fullscreen unless you use the 2nd G-SYNC option and that has some issues with normal desktop stuff.
 
Aye I've been running full screen. I dunno if anyone has WoW or D3 installed but I'm confident you should be able to replicate what I described in my previous post:

GSYNC ENABLED
Use The Advanced 3D Image settings : Global Settings : Vsync ON

Try running D3 / WoW with ingame vsync off - FPS goes above 144.

Enable ingame vsync, FPS caps at 144.

So with that in mind, and the fact for FPS (csgo etc) I don't want Vsync to enable at 144, I want to find out if running with NVCP Vsync OFF, with ingame Vsync ON on a per game basis is viable? Will it effect Gsync operation doing so?
 
If you put vsync on in game, it will stop G-Sync working. I wish they would go back to the old way although I can see why they have done it this way.
 
  • G-Sync on - V-Sync on (in the NCP) = max monitor refresh rate G-Sync
  • G-Sync on - V-Sync off = G-Sync working till the frames go over your monitors maximum refresh rate
  • G-Sync off - V-Sync off (or on) = No G-Sync

Do not enable Vsync in game or it will not let G-Sync do its thing.

Hope that helps.

The only problem I have is that running with:

[*]G-Sync on - V-Sync on (in the NCP) = max monitor refresh rate G-Sync

It appears not all games obey the vsync @ 144fps, meaning my frames go over 144. WoW is one example.

Also I'd prefer to just run:

G-Sync on - V-Sync off = G-Sync working till the frames go over your monitors maximum refresh rate

As to reduce input lag for shooters, and then I'd run vsync on a per game basis via their own ingame settings. You are certain ingame vsync enabled messes with gsync?

I wasn't 100% on what was what to start with and noticed tearing (something I have massive disdain for) and did the usual Google search to see if anyone else was getting it, found the Geforce sight and followed what was said there.... However, I misread it to start with and put V-Sync on in game (Elite Dangerous) and no tearing but I did notice a bit of stuttering now and then (not much), re-read the Geforce site and realised my mistake and turned Vsync off in the game and 'hey presto', all smooth and no tearing and locked at 144fps (my monitors max refresh).

I don't have D3 to see what is what though sorry but I have never seen any of my games go over 144fps with G-Sync on and V-Sync on in the NCP. Also I am rather old and slow, so a little input lag won't make diddly squat to me in twitch shooters :D
