Skyrim, Fallout 3 and New Vegas: major mouse issues

Solution 1:

"Up until the driver update it worked", roll back your driver. Make note of any additional settings that disappear, and any different settings.

Skyrim: how to fix input lag and vertical sensitivity for mouse and 360 controller (PC) -YouTube

Most of these are ini tweaks. Try lowering your pre-rendered frames in the Nvidia control panel to 1. Cap the frame rate at 50fps.

Alternatively: (GameFAQs, --Helfire-1)

Enable adaptive Vsync (half refresh rate)

Enable triple frame buffering

Pre-render 3 frames

In the ini file: Mouse acceleration off {add bMouseAcceleration=0 to [Controls]}

In the standard options: Distant object detail (medium)

My settings: (Like in the video, it also took me 9+ hours to get Skyrim playable and like you I forgot half of what I'd done)

fMouseCursorSpeed=2.000 (fixes annoyingly slow menu cursor)

fMouseHeadingSensitivity=0.2000

fMouseHeadingXScale=0.2000

fMouseHeadingYScale=0.2000

The above allows you to make 180 degree turns in a single gesture, also:

bFXAAEnabled=0

RadialBlurLevel=0

bDoDepthofField=0

bDoHighDynamicRange=0

bUseBlurShader=0

bGamepadEnabled=0

Interestingly, I find no MouseAcceleration setting in my ini (I'm unsure how many problems SkyUI and SKSE have solved for me.)

If you have applied any ini tweaks, DO NOT adjust anything from the in-game menus.
