1.Press 'Home' on your keyboard to bring up the ReShade menu.
2.On the menu's Home Tab, confirm the default preset you prefer to run without NVGs is selected first in the drop-down menu (blue bar at top).
3.From the drop-down menu, select the 'white phos.ini' and click 'Select'.
4.Click on the Settings Tab. Under 'General', find the 'Next Preset Key' option and change input to whichever key you want to use as a toggle between your presets. I found 'H' as the best option as it allows me to press it simultaneously with 'V' when I turn on or off my night vision.
5.Use your new hot key to toggle on the white phosphor NVG preset on when you hit your key bind for 'Cycle Vision' (default is V).
