Xbox / Windows PC games not able to smoothly move camera with a mouse

I have a very comfortable trackball (a Logitech Marble Mouse) which I bought to alleviate my mouse knuckle. i just hold down the w and use the camera (trackball) to move smoothly. But sometimes I try to move by holding down the left button which is what
i do in Diablo (I think) and end up shooting someone instead. oops! lol I need to go back into Diablo which I have been playing more since the revamp and see what's causing this because I know my primary and secondary attacks are also on the mouse buttons.
i dislike having to use the keyboard for any common actions. I don't mind hitting a key for map or inventory but moving is a different matter.

I will put my money on it being used for the decryption mini-games. That is because they will be able to use the same system on the PS3 with the Move and on the PC with the mouse.

Okay thank you very much, I have one small question when it comes to streaming. If i were to stream an Xbox 360 game from an Xbox One to my Windows PC, would I be able to control that streamed game with my mouse and keyboard as opposed to a controller while
on my Windows PC playing the streamed game?

No, only controller. You can't use mouse and keyboard in this fashion for any games over xbox one streaming.

Ok, thanks, I will try that one. It doesn´t seem possible to "move" the camera to one direction than (the longer you "press" POV < the more the camera moves to that direction). I will get used to use the mouse for that instead.

Hi,

The Xbox One controller can not move the mouse, at least not on it's own. To move the mouse - or emulate the mouse - would require third party software. As for games, it depends on the game. While many PC games support the Xbox One controller from the
get go, some games need to be configured to use the controller.

What game are you trying to use with the controller?
