G-sync Fullscreen Windowed Issue

Hi

I'm having issues with enabling G-sync while running in windowed fullscreen. If I use fullscreen G-sync activates fine.

The thing is if I enable G-sync for windowed and full screen mode it will work fine until I open a youtube video on my other screen (both are 165hz) then g-sync will deactivate. If I swap off Hardware acceleration in Google chrome I can watch the youtube video and g-sync work fine in windowed fullscreen, but then my browser is lagging and stuttering a lot. So

G-sync + fullscreen + youtube on other display = fine
G-sync + windowed fullscreen + youtube (hw acc on) = not fine
G-sync + windowed fullscreen + youtube (hw acc off) = fine

I also tried changing settings with Nvidia Inspector, Under the GLOBAL_DRIVER_PROFILE

I have tried setting g-sync to fullscreen only

and then under Path of Exile profile I changed the g-sync to fullsceen and windowed

This doesnt seem to do anything for me and its still not working.

This do actually work fine for other games like World of Warcraft, so I dont know if this is a specific problem for Path of Exile?

I'm on latest windows 10 update (2004) and latest nvidia drivers and I had same issue on previous windows 10 version (1907).

It doesnt matter if I play with Vulkan or DX11 its the same issue happening.

I have a similar issue, though with two monitors with different refresh rates (144hz / 70hz). Sadly, disabling the hardware acceleration doesn't do the trick for me, so im playing with a shitty frame rate.

I played a few games, but it only happens with PoE, not sure why.

But i've tried the same stuff with no success. Really frustrating having to play with an horrible frame rate with your config is more than capable of running it smoothly... :/
