Hey, I decided to download The Witcher 2, and while left-clicking allows me to skip the opening cutscene, the mouse straight up doesn't work after that. In fact, neither does my controller. I'm able to use my mouse again upon alt-tabbing out, but going back into the game renders it inoperable again. The menus are working fine, as evidenced by the moving backgrounds, but no inputs are being received, and I can't do anything.

Worked like a charm. Thanks a ton!

Please can you help me? I can´t find useMouseDamp in User.ini... And the mouse is still not working...

What to do if theres no useMouseDamp=true i tried to wirte it in but still nothing can you help me?

Make sure you're opening User.ini in C:\Users\<Your Username>\Documents\Witcher 2\config
Look for the [MouseInput] section and add it there

[MouseInput]
...
UseMouseDamp=true

One problem could be, that you're running the game with another user, thus another User.ini is used.
Browse to the correct user and edit the User.ini there
C:\Users\<Your Username>\Documents\Witcher 2\config

Thanks solved it the problem was that i installed the game on another user :D

Great, thanks for the feedback.
