    Hello guys,

    I have buy a "MSI GTX 1080 TI Gaming X Trio" yesterday, and when i run a game like GTA V or Fortnite, i have big tearing on my screen. Of course i have G-Sync and Vsync ON.

    When i turned G-Sync option OFF with V-Sync ON, the tearing desapeared.
    I have tested with force ON "Fast Sync" in nvidia pannel, and G-Sync ON, and the tearing desapear too.

    My question is, why i have big tearing with waves on my screen when the G-Sync is ON and V-Sync ON or Forced ON ?

    If anybody are in my situation, for be sure i don't have a GPU failing.

    Sorry for my English, i'm French.

    I was in test with V-Sync OFF en G-Sync ON, and i have tearing.... I think 165hz G-Sync monitor is pretty good than my 60hz G-Sync ! When i return in Fast Sync it's ok, and my G-Sync is activated, i don't no why :( I don't have this issue with my SLI of 970, and now i have a single gtx 1080 ti, i have that !

    What's your framerate in-game?

    My frame rate is 60 fps when i turn V-Sync or Fast Sync ON with G-Sync activate.

    I finally find the source of my problem, i explain for other people encounter that same problem !!!
    I have the latest nividia pilote 388.13, but i didn't have the new Windows 10 MAJ 1709. Now it's work properly :cool:

    Odd to hear a Windows update fixed anything.

    Keep in mind Adaptive Sync can get tearing if it hits the maximum refresh rate of the monitor. Set a limit of 2 fps lower than your max refresh rate to avoid that.

    (Off topic.)

    60Hz gsync... that's a lot of input lag when you actually reach 60FPS. If you want to have less input lag, consider capping your frame rate to 58FPS with the game's limiter (if it has one) or RTSS.

    ^ What RealNC said.
    Cap fps to 58, Vsync On, Gsync On.

    Gsync works only within your monitors refresh rate range, not above it. Anything above will cause tearing.

    Thanks people for your tips. I turn vsync on in the nvpanel with 58 fps lock in RTTS and it’s better like you said !

    Yes, I didn't believe it either, but it really does feel more "fluid" than unlimited FPS, especially playing shooter games online.

    V-sync and g-sync up to frame times of no less than 1/60 s (60 hz) shouldn't result in tearing.
    What happen above whatever one prefer tearing or sticking to 60 fps is up to each and every one but what I would expect would be that v-sync + g-sync would result in lock 60 fps when more is possible and no tearing. But obviously your experience is different.

    Regardless fast sync should be better than v-sync and that give the result you expect and want so just use g-sync and fast-sync then :)

    I have tried G-Sync and Fast Sync with 58 fps lock yesterday, and i think it’s better than VSync, maybe it’s juste on my mind.

    When using a frame cap, fast sync is not useful with g-sync. It can be either just as good, or worse since it can frame skip with some games.

    When not using a frame cap, fast sync is somewhat useful as it prevents tearing when g-sync gets disabled, at the cost of microstutter.

    So when using a 58FPS frame cap in order to be within the g-sync range 100% of the time, fast sync does not make sense.

    I understand, if i resume this is better to play G-Sync with Vsync ON, or Fast sync without G-Sync.

    Another thing i not understand, is it normal to have tearing with only G-Sync activate and framerate cap to 58 without Vsync ?

    Feels like something is wrong with your driver installation.

    I have a 1080Ti and I play on my 4K TV without any tearing whatsoever. I use the standard setting I always use which is V-sync on in NVCPL and V-sync off in games (except those games that don't care about NVCPL where I need to enable it in games).

    Of course the TV does not have G-sync but should that really be an issue?
