Oh yeah would that effect external monitor as well as the external monitor doesn't have gsync.
I have tried taking this laptop to the Asus service centre 3 times and they have been unable to fix the issue. They really don't know what they are doing.
This happens in multiple games. I have done a clean reload of windows 10 new drivers. Latest NVidia drivers, ive done the drivers from the Asus website.
After sending it back to Asus service centre they did a clean install of Windows 10 plus drivers however the issue still remains.
I know its an issue to do something with this model as I have a G752V with the 980m which works fine.
Any help would be greatly appreciated.
