MOUSE & CAMERA FIXES On the PC:
GET A GAMING MOUSE. A cheap option that works ok is the Sharkoon Fireglider (black version)
Open WINDOWS Mouse control panel and DISABLE "enhanced pointer precision", then set pointer speed to midway, or one notch up from midway.
Then open Skyrimprefs.ini and set the following lines:
[Interface]
fMouseCursorSpeed=1.0000
[Controls]
bMouseAcceleration=0
fMouseHeadingSensitivity=0.0160
Then open Skyrim.ini and set the following :
[General]
fdefaultWorldFOV=95
fDefault1stPersonFOV=95
for wide angle view, suitable for widescreen monitors. The game's default is 65 which is for consoles runing on TVs
[Controls]
fMouseHeadingXScale=0.0200
fMouseHeadingYScale=0.15
The lines in blue are crucial. The lines in green are my preferred mouse settings, which you can experiment with. My in-game mouselook sensitivity is set to low, reflected by
fMouseHeadingSensitivity. I use the already mentioned gaming mouse which has a higher sensitivity than normal mice.
For combat try the following camera settings:
In 3rd person view when you draw weapons or spells it will position the crosshairs slightly to the side and place the camera behind you and slightly above you, and will make the transition from 1st to 3rd person POV almost instant.
