It seems we might be using the same drivers. I looked through the newest ones, but unfortunately there’s nothing about resolving the low FPS issue in fullscreen borderless.
Consider using another driver version. Turn off V-Sync if it's active. Verify your monitors' refresh rate settings in Windows—ensure it isn't set to a different value than the native rate. I experienced a problem where the refresh rate changed from 60Hz to 30Hz on my main monitor, affecting only the desktop and non-fullscreen games. Edited December 6, 2016 by iiMaagic missed an 'and'
I also rely on a G-Sync display and consistently turn off V-Sync during gameplay. Occasionally it attempts to reactivate after a driver change.
I also use a G-Sync monitor and have faced similar problems. The issue often stems from the driver. At times simply removing the driver entirely—clearing it and the associated software from your PC—can resolve it, while other times Nvidia provides hotfixes for the specific driver. You’ll need to visit the Nvidia forums to locate these updates.
