The new logitech software will actually save your settings even, even after you restart your pc.

It seems silly that it took this long to have a solution to this on going problem.
As the program is in early access, hopefully the settings get a bit better and we get a gain setting.
I have not tested this with any other logitech webcam product so I cannot comment on those.
Let me know in the comments below if this worked for you!
