[ZeroTolerance]

TO INVERT MOUSE:

From the User.ini in Documents\Witcher 2\Config:

[MouseInput]
KeyboardCooldownSpeed=0.1
MouseDampX=7000
MouseDampY=7000
MouseSensitivityX=0.18
MouseSensitivityY=-0.18
MouseSmoothness=1
SensitivityX=0.5
SensitivityY=0.5
Smoothness=0
UseMouseDamp=false

Change the MouseSensitivityY setting to a negative value and presto, your mouse is inverted. Quick fix until CDPR adds it to the menu in a patch, if they do.

Invert Gamepad Y Axis:

First of all, make sure you're editing the ini's in the Documents/Witcher 2/Config folder, NOT the game installation folder (this took me hours to figure out :<...)

Anyways, open the User.ini file under ...\Documents\Witcher 2\Config

check the KeyboardLayout= property, for most people it should be QWERTY. close the file without saving.

Assuming it is QWERTY, open the input_QWERTY.ini in the same folder, find the IK_Pad_RightAxisY=(GameKey="GI_AxisRightY",Value=1) and change the value to -1.

IK_Pad_RightAxisY=(GameKey="GI_AxisRightY",Value=-1)

Save and exit. I tried this and it worked for me.
