when I'm in the menu or looking around in-game i have mouse lag. i don't lag when playing it's only my mouse and its very irritating is there a patch or a fix for this?

have you tried turning down the Graphical Settings?

maybe you can give us your System Specs

Windows 7 Home Premium 64 bit

intel core i5-2500k CPU @ 3.30GHz

8g ram

NVIDIA GeForce GTX 560 Ti

and i tried lowering the Graphical setting to see if that might of been the problem but it didn't fix it.

mods? Graphical mods like enb series, texture mods, weather mods, etc?

What kind of framerates are you getting?

Go to your SkyrimPrefs.ini < C: \ Users \ [Your UserName] \ Documents \ My Games \ skyrim >

Go to section:

[Controls]

and change: bMouseAcceleration=1 to bMouseAcceleration=0

----------

And try to go to your Nvidia control Panel and change Maximum pre-rendered frames to 1
