    G-Sync doesn't work properly if you don't enable VSync as there is tearing. The first two pages explain why. VSync when enabled alongside G-Sync is not actually VSync, as long as you limit the FPS. It simply enables the frame time compensation algorithm that prevents tearing inside the G-Sync range caused by frame time variances.

    G-sync will work without V-sync, V-sync is simply used for when G-sync is out of scope (potential frame rate produced is higher than monitor refresh rate)

    No, G-Sync does not work with VSync disabled because otherwise there is tearing inside the G-Sync range.

    G-sync works by timing a completed frame to a refresh of the monitor. If you had to have V-sync enabled it would make G-sync kind of pointless.

    Did you not read the Blur Buster's article? Anyway I'm done repeating this. You can see the tearing yourself in the pendulum demo (test pattern) below the refresh rate with G-Sync on/VSync off on a G-Sync notebook.

    "You know nothing Jon Snow"...
    I use G-sync monitor for 4 years and I tested all setting I have read about it, and the best way to work with g-sync (have no tearing effect) and almoste NO INPUT LAG is to use g-sync with v-sync "OFF" and limit fps 1-3fps below yoru max refresh rate.

    In my case I OCed my IPS to 100hz so I limit fps to 97 fps and i dont have any tearing in 30-98 fps range I asure You.

    V-sync "on" is used in g-sync only for limit fps but side effect is input lag. U can feal this very badly in fast online FPP games.

    There is one more think. All depend about GPU drivers. On some with G-sync "on" and V-sync "on" was almoste no input lag and works as fps limitter to max refresh rates and on others drivers
    causes input lag.


    (ps. I write "almoste no input lag" becasue some people claim that g-sync adds a little input lag. In my opinio it's so little that I can play on high level online FPP games and have very good aim. On V-sync "on" is impossible)

    @Z3us_PL

    I agree with the frame limiting part (3fps lower with RTSS for eg.), but according to the previously mentioned article, v-sync doesn't interfere with g-sync withing g-sync's range, so that v-sync input lag would only be felt outside g-sync's range.

    Gsync only works with in the refresh rate of your monitor, as soon as you're out of the window it no longer works. Eg. 35 - 144hz. Way to get around this is either cap your fps to the max refresh rate of your monitor, vsync or fast sync. I personally use fast sync because to me it feels just like gsync without and of the crap that vsync has, but I've been told im wrong.

    Fast sync has worked pretty well for me too.
