Creators Update breaks Windowed G-sync; here is the fix!

Sometimes, trouble comes uninvited as has been the case for Windows 10 Creators Update. Recent reports suggested that Creators Update breaks Windowed G-sync. A user of Windows observed, that the new build breaks Windowed G-Sync following the installation of driver 381.65 and running it with both AU and CU (with DDU after installing CU).

Initially, there was a good performance during benchmarks but later some issue was experienced with G-Sync and CU. To be precise, Windowed G-Sync seems to be broken. Moreover, while playing a game on Windowed/Borderless Windowed, stuttering and FPS jumped from 50-100 in no time. This was not to be seen with the same driver version with AU before I updated and the problem was solved once back to Fullscreen.

A Reddit user who faced this problem has also posted how he fixed the problem. Perhaps it will help you if you too are facing this issue.

Windows 10 breaks Windowed G-sync

Access ‘Control Panel’ and go to System and Security. Thereafter, navigate to Power Options

Left Click “Choose what the power buttons do” option and hit the “Change settings that are currently unavailable” button.

Now, simply uncheck “Turn on fast startup” and restart your computer.

As of now, there appears to be no solution in sight for G-Sync issues on full screen however, NVIDIA has acknowledged this problem and assured to fix it, soon.

Developed by NVIDIA, NVIDIA G-SYNC is a proprietary adaptive sync technology that aims to eliminate screen tearing and offer a smooth, fast gaming experience. The technology enhances the performance by synchronizing display refresh rates to the GPU in user’s GeForce GTX-powered PC and minimizing display stutter. The result of this event, scenes appear instantly, objects look sharper, and gameplay is super smooth, thereby offering users a stunning visual experience and a serious competitive edge.

    I’m pretty sure it’s gsync as well.
    I’m playing The Witcher 3 mostly but it happens in all games.

    This method didn’t work for me though. I’ve done the following:
    – Disable Game DVR in the xbox app and trough the registry
    – Disable fast boot
    – Restart
    – Disable VSync
    – Run full screen, borderless window and windowed

    The FPS still drops from a steady 60fps on ultra before the update to 30 fps at best.
    I’m running an i7-7700k with 32gb of ram and a GTX 1080 SLI so no bottlenecks there.

    Hopefully it will be fixed soon because this is unbearable!

    me too, don’t worry nvidia will change parameters and we will find back enjoyment of G-Sync !
    i was a few disturb yesterday then i just switched for a gtx 1080 ti in same time.

    2 solutions :
    – disable g-sync if you are over 60 fps and active v-sync
    – try to be between 30-60 fps but not over 60 fps with g-sync

    In this case you will have g-sync activated betwen 30-60 fps or v-sync if over.

    Good enjoy and wait for the fix !

    With my current setup I hit the 60fps cap with gsync enabled.
    Now however, no matter if gsync/vsync is enabled, it wobbles around 20-35 fps.

    Guess we’ll have to wait and see… very frustrating
