Is G-sync enabled whenever you run a game?

Only when gaming, and significantly, only when gaming in full screen mode. (Some games have options for borderless full screen and windowed mode)

You can turn gsync off in the nv control panel if you wish/ for testing too, if you want.

Alright cheers, like Im playing far cry 4 atm, and theres a option in the video settings for V-Sync on, that wont do anything will it?
 
Far cry 4 is not the best of games to test with if you're after decent results with G-Sync, at least not on my end anyway. However, Max Payne 3, Sleeping Dogs, Crysis 3, and Tomb Raider blew my mind with G-Sync enabled.
 
No worries bud. I was also under the impression before I got the Swift that I would have to do this. It was only by actually using it that I discovered it's not actually necessary to disable vsync in game for Gsync to work properly.
 
One thing to note with g-sync is never run a game at the max fps your monitor can achieve as you will encounter heavy input lag. You need to limit your fps just under when using g-sync to avoid this.

I've read about this, but I can't say I've ever noticed any, and certainly not severe input lag when running games at a constant 120fps (I run my swift at 120hz all the time for convenience).

Maybe I'll have another look to check properly. There aren't many games I play that can achieve a constant 120fps anyway so perhaps I've never really encountered it? Are you sure about this?
 
Gsync reverts to vsync when framerate matches refresh, so you would be better off running 144hz and capping frame rate to 120hz, any downsides from 144hz mode should still be avoided but you get the full gsync effect all the time

Vsync input lag is still only about 20ms so notmhuge and you may not notice it, but if you can get rid of it you may as well

Yeah I read this so I started using Riva Stats that comes with Afterburner to set it to 59fps max.

Say for example, I wanted to play Skyrim and cap at 60fps. I've been setting my monitor to 60hz and allowing G-sync to cap automatically. Would I be better setting refresh rate to 120hz constantly, and using 3rd party software (sometimes even the game software) to cap frames at 60?

Not for skyrim, I know that much. Skyrim is weird when it comes to vsync, gsync, the built in physics engine, SLI, and certain types of stutter. I've spent weeks getting skyrim, one of my favourite games ever to run butter smooth, stutter free with gsync. I had to write myself a proper readme file so I know how to do it in future. Input lag I don't care about with this game.

If you run gsync and SLI, which looks like you do in your sig, my solution may make you want to marry me.

Ok bud here you go. These are notes I made after A LOT, and I mean a lot of experimenting trying to get Skyrim to run smooth with Gsync and SLI. NOTE I'm using an ENB....

---------------------------
NEW FIX DISCOVERED BY ME AT OCT 2014:

(NOTE: This fix seems only good and worthwhile for gsync monitors as it appears to disable vsync, even if it's enabled in the 'enblocal' file. )


1. Download "Skyrim Stuttering 64hz Bug Fix" from Skyrimnexus.

To install, put the d3d9.dll and antilag.cfg in the Skyrim executable directory.

As I am using ENB it's therefore important to do the following:

- rename the d3d9.dll file from the Skyrim Stuttering 64hz Bug Fix to "other_d3d9.dll". In the enblocal config file make the proxylibrary use this new one. So it looks like:
[PROXY]
EnableProxyLibrary=true
InitProxyFunctions=true
ProxyLibrary=other_d3d9.dll

The ENB I am using was using a ProxyLibrary entry here for "d3d9_smaa.dll" but on testing I see no bad effects from not using this, and anti aliasing can be applied through the ENB settings anyway (just use Edge AA)!


You can edit the antilag.cfg file, but the default values of RenderAheadLimit=2 and FPSlimit=60 are best


2. Open up your Skyrim ini file in your Documents\my Games\Skyrim folder and add the following line under the [General] section at the top:

iFPSClamp=60


With these fixes, it is so so smooth, and gsync really works well too if the framerate dips below 60.
The only problem is using the iFPSClamp=60. If the framerate dips below 60 the game goes into very slight 'slow motion'. Lower the framerate the slower the motion. As I have a good system it rarely dips below 50fps, so it's the best trade off all round.

Without the iFPSClamp=60 command then you don't have any 'slowmo' issues, but it's just not as smooth, There is slight judder when panning round. Probably would have thought it was ok and smooth if had never tried the iFPSClamp fix!

3. If both cards are pegging along at 95% usage, especially in tree areas (using vurts flora overhaul latest mod 2.0 alpha and above), to save a bit of GPU strain, Turn off ambient occlsion in the EFFECT setting area of the ENB, and enable 'performance' level AO in the Nvidia control panel for the game profile instead



OTHER INFO BELOW THIS LINE TO BE CONSIDERED REDUNDANT

-------------------------------------------------

Apparently there is a 64hz 'bug' in Skyrim. Only just found out about this so basically the fixes I was trying to do (using fps clamp at 60 and frame limiting at 60) were causing their own issues. THE KEY IS TO SIMPLY USE VALUES OF 64......OR.....59. Anything but 60 itself.

FIX:

1. Edit enblocal file in SKyrim directory so it looks like this for frame limiter:

[LIMITER]
WaitBusyRenderer=false
EnableFPSLimit=true
FPSLimit=64

and then vsync off under [ENGINE] like this:
EnableVSync=false \\Don't NEED to do this, can leave true if like


Set monitor refresh to 120hz for best results with this too.


2. Open up your Skyrim ini file in your Documents\my Games\Skyrim folder and add the following line under the [General] section at the top:

iFPSClamp=64

(NOT 60!)


AMAZING RESULTS! Feels as smooth as tombraider almost, and GSYNC is definitely working properly as the usual choke points where it would drop to low 50's fps are now smooth! So - if there are any jitters/ judders, something is not right again.

However, some areas like swamps outside Morthal make the framerate go down to the 40's and the GPUs don't run full pelt like they should. When this happens here it feels laggy and sluggish (this may be a Gsync/ current driver issue?), but if you move away it's fine, and if fast travel to another area, it's fine, so consider THIS A FIX. (Before, when using iFPSClamp=60 the framerates and laggy feel would persist for some reason).

P.S. If you mess with the fps limit numbers in the built in game enb menu it can mess up and go to 59.9999999 etc etc when you check the actual enblocal file, which causes micro stutter too! Only make changes manually in the enblocal ini file.

:) Let me know your results, I'd be interested to see how you get on. I have loads of fixes like this by the way for games. Stutter and judder in games and getting rid of it is almost a hobby!

This is why I leapt on a gsync monitor now, as it goes some way to the holy grail of smoothness. BUT, gsync is NOT a fix all for bad coding, bad engines, weird engine issues, and gsync itself can cause issues when using SLI in some games too. Gsync is brilliant, but not a miracle worker.
