If your on PC.
Go find where your saves are on your pc and In that skyrim folder there is a SkyrimPrefs.ini file under [Interface] there is a line fMouseCurserSpeed=1.0000 Change the 1 to a 2 or some other number and it will speed up your mouse curser ingame.
I did that after googleing how to increase mouse speed in skyrim i clicked the link on top n followed that little bit of info at the bottom and it worked for me
The link.. I would post a direct link to where i found the info but i dont have permision yet lol.
As far as Console commands i have no clue if there are any for it.
Woo Very first post on these forums /wave
Edit: For some odd reason it was telling me i could not post links even tho i took out a link i put in :/
i posted Test post. then edited that out then added all that up there
Thanks for the information guys, this recommendation is working perfectly, but only in the menus. Anyone know the command line that can be edited to adjust sensitivity during game play? I am suprised I can't find a console command. With my mouse (g500) i use med dpi and 3.5 sensitivity in all my games. I don't want to use the slider because it doesn't tell me the exact sensitivity number;) I play alot of different FPS's so I want my aim to remain consistent when I change from game to game. Setting the sensitivity via console or config gives me complete control over the setting. Sliders only let you guess what feels best.
