A free mod for Fallout 4, by deathclay.
If you like the idea of removing the half-second delay when zooming in with a scope, but don’t want to wait for that whole second to see what you’re looking at, then this mod will remove it for you. You can try out the other versions as well.
Additionally, you can use the values listed below if you like Angryglock's approach:

for 50%, 75%, and the lowest setting possible, respectively.
Add the following to your Fallout4Custom.ini if you wish to eliminate a further delay from your game:
fEnterWorkshopDelay=0.01
By doing this, you'll be able to enter workshop mode without having to hold down the assigned key.
