How do I turn off mouse acceleration in Skyrim?

Question

Mouse acceleration seems to be on by default, and I can't find anywhere in the launcher settings or the in game settings to turn it off.

It's very annoying as it makes it feel as if the mouse is lagging. Is there any way to turn it off?

If you shoot the skeever from stealth, that mouse won't be doing any acceleratin'! — tjd, Jul 13 '16 at 12:24

Go to \Users\[Username]\My Documents\My Games\Skyrim
Open the SkyrimPrefs.ini file with notepad
Find the line bMouseAcceleration=1 (located under [Controls]) (If there is no line, add it)
Replace the 1 with a 0
Save the file (make sure you don't accidentally save it as SkyrimPrefs.ini.txt)

Also turning off Vsync seems to help mouse lag. – Arkive Nov 11 '11 at 01:56
2 things: Firstly, how do I turn off vsync, can't find it anywhere. Secondly, I've looked in both my skyrim.ini, and my skyrimprefs.ini and the "bMouseAcceleration=1" was in neither, and putting it in either myself (with a 0 instead of 1) didn't fix anything. – Mr Smooth Nov 11 '11 at 02:44
@MrSmooth: To disable VSync add "iPresentInterval=0" to the bottom of the [Display] section in Skyrim.ini bMouseAcceleration should be in the SkyrimPrefs.ini under the [Controls] heading. Editing answer to reflect that. – Arkive Nov 11 '11 at 02:59
Ok it wasn't there, but I added it there, and now mouse acceleration is off (don't know whether it was the vsync though, but whatever). – Mr Smooth Nov 11 '11 at 03:04
I couldn't find "bMouseAcceleration"... is it about Xbox360 controller? – Nov 18 '11 at 14:48
@Sardun bMouseAcceleration is about a computer mouse. If you don't see bMouseAcceleration, then add it under [Controls]. – Arkive Nov 18 '11 at 16:53
there is a folder in the steam files as well as my documents, which should I edit? I did both, but is it necessary or does one override the other? – Nov 20 '11 at 16:02
I added "bMouseAcceleration" under [Controls] but it still doesn't fix it. Though "iPresentInterval=0" did fix this problem in the menus, the mouse delay persists. – Nov 22 '11 at 02:16
