I had Windows 10 update (3-4 November "Fall Creators Update") and after this G-sync stopped to work in myPrepar3D v4.1 (full screen, only on windowed mode it works).

I reinstalled drivers, did clean install of 388.13 drivers (now) and the same. On FULL SCREEN G-sync dosen't work here.

Tested few options - it works now in windowed mode only. Not at Full screen.

Did You notice the same issues after this big update of W10 (if You are user of G-sync monitor)?

It has been stated on AVSIM and many other places that P3D 4.x NEVER runs full Screen, it is always windowed even though there is a selection under view tab for full screen. G-Sync will only work with P3D using G-Sync windowed mode.

I have an ASUS P279Q, 27", 1440p, G-Sync monitor, and I have G-Sync set to full screen and windowed mode and it works great.

It works before for me, but with windowed mode (P3Dv4) I see frames (alt+enter), this is not a good solution.... :(

 

It looks really poor as "window", not for me:

in this situation G-sync works, with alt+enter (full screen) not

 

Check in the Nvidia Control Panel that "Enable G-SYNC for windowed and full screen mode" is ticked.

I have not had any problems with G-SYNC either before or after the Fall Creators Update.

Do You have drivers 388.13 of GeForce?

Maybe the problem is here. For sure I have ticked + the same in NVidia Inspector.

 

Do You have Academic version?

Btw.

checked 388.00 the same so this Windows update do something with this.

I found interesting post from here: 

Will try Tomorrow.

I'm using 387.92 at the moment, and I have the Pro version, but that should not have anything to do with it.

Tested:

No, it dosen't helps, it's a case of new kind of stutter, nothing more.

 

 

Hi,
I checked also drivers: 387.92, 388.00 and 388.13.
The problem with G-sync after this W10 FCU update is present still.
So looks like the problem is driver together with Fall Creators Update of Windows 10.

Before this  Fall Creators Update Windows 10 udpate G-sync works fine here!

I did video to show it.
The problem is full screen now and only. 
Refresh rate of monitor is set to 60Hz so max FPS with G-sync on must be 60 (the same like with V-sync, here is off for sure). It works if the title is in windowed mode (what is not acceptable, looks very odd and badly simply!). In this situation G-sync works and no screen tearing. If I change a mode for full screen (Alt+Enter here) G-sync stops work. I see screen tearing, annoying micro stutters and FPS without limit of Hz of refresh rate of monitor. In GeForce panel G-sync is ON as Full screen + windowed. I check also others options with the same result.
