    I usually set VSYNC to FAST but I just read a post on the nVIDIA forums saying VSYNC adds input lag and it must be disabled and leave GSYNC on then one would not get tearing but no input lag

    is this true? :stewpid:

    Leave VSYNC ON and don't set it to fast.

    Vsync will turn on when your FPS hits the max refresh rate, therefore you should limit your FPS ~3 less than your refresh rate.

    What do you want? What monitor do you have?

    My monitor is X34, and its upper bound is 100Hz, which is fast but not fast enough to not have noticable tearing. So I keep VSync ON, as I hate tearing more than input lag on 100Hz.

    If you have, let's say 144Hz monitor, you can experiment VSync OFF and see if you can even see screen tearing above 144FPS. If you see, and turn VSync ON, is the input lag too much for you?

    Unless recent events changed things, the best all-round solution is VSYNC off, global FPS limit a few FPS below monitor refresh rate.

    Turn vsync off limit your fps ingame

    I do both off.
    Honestly, I don't think it really makes a difference if you are using a FPS limiter. Either way Gsync can function fine.
    At least with Vsync off, if Gsync is not working you will see tearing and know something is wrong.

    I agree. Have 100Hz monitor, I limit my fps to 95 fps and let gysnc take care of the rest. I try not to have my fps drop to below 60.

    I'm enjoying the smoothest/lag free gameplay I've ever experience.

    I don't use a FPS limiter, just let Gsync take care of it all.

    FPS limiter doesn't work in all games, Skyrim:SSE is one (before the FPS lock patch) which produced a number of weird artifacts.

    I've noticed that some games don't give a rat's ass about the settings in NVCPL :/ If I notice jitter or micro stuttering I toy around with the V-sync settings both ingame or in NVCPL since the two can sometimes work against eachother.

    Vsync needs to be set to ON in NVCPL.

    Otherwise you get tearing despite being within GSyncs frequency range.

    May only affect certain setups/monitors but if you turn off Vsync Gsync works(no stuttering) but tearing still occurs.
    This has been reported by many.

    Turning on Vsync results in no tearing and as long as you have FPS limiter it never activates.
    So you're not being hurt by it being on.

    In that case, Vsync would be taking care of it all if your FPS is at your refresh rate.

    That defeats the purpose of gsync.

    I don't use any FPS limiter and have smooth video (ie fo4 100 -50). My acer predator 34" is 100 refresh.

    I don't think that's how it is supposed to work. Maybe you have a defective screen. If you are getting tearing with GSync on, then that completely defeats its purpose. You do not need to have VSync on for it to work properly.

    I'm not saying you are lying, but something is obviously wrong with your set up.

    No it's nothing wrong with my setup.

    It's a driver issue, intentional or not, or a Gsync firmware bug affecting many people.
    Doesn't matter the monitor, I've seen it affect different brands.

    Not a hardware issue for sure.

    Vsync ON is required for many people, you can google it and get many results.

    Most likely a driver issue as VSYNC on doesn't turn on Vsync when you are within GSync's range but it does eliminate tearing.

    If you have 100FPS constant you are using Vsync not Gsync.
    Doesn't matter if it looks smooth to you, that's just how it works.

    Sorry but I agree with Agent since I have the exact same problem and a 1st generation G-sync module. Plus, let's not forget that the G-sync part in the drivers was overhauled (for the worse in my opinion) a long time ago.

    I don't have constant 100fps, dips to as low as 50fps (some cases like 27-35 in certain locals) and hoovers between that and 100. Depending on local, but all smooth. Just saying, did my due diligence on research and am satisfied with accepted results. Not saying current accepted findings could not be rejected, but not convinced yet.

    OBTW, doesn't gsync act as the fps limiter in some compacity?

    I was also thinking this. On my 1st gen Swift, if I use the button on the monitor to go between 60, 120, and 144hz, the fps doesn't exceed whatever is selected. And I just verified again that I don't have any form of vsync on.
    For example, if I load up CS:GO and have the monitor set to 60hz, the fps will be limited to 60. As soon as I change it to 120, the fps will jump to 120, etc.....

    No it does not.

    Vsync ON limits the FPS to the refresh rate in which case gsync will be disabled.

    FPS will exceed refresh rate with Vsync off


    Vsync is on in your case, it is being enforced somewhere.

    Gsync cannot cap FPS, only Vsync.

    Try forcing vsync off globally with nvidia inspector.
