Okay so my mouse lags alot I can't even enjoy the game. Everyone says to go to your Steam Dictionary but where is tht ???

Turn off Xbox controller check box. Under game settings.

BUT I DON'T HAVE AN XBOX I HAVE A PC

He wanted to tell you, to turn off, all features that you don't need.

He meant the xbox controller option in "System>Settings>Gameplay" but what I found works is going to Skyrim's installation folder which if you installed from steam would be in the steam folder so something like C:\Program Files\Steam\steamapps\common\skyrim then going to the Data folder and editing SkyrimPref.ini.

Search for mouseacceleration and if at the end it says "1" change that to "0" and save then exit the file. You can edit it in notepad.

In view of the totally nonsensical minimum requirements, people with terrible graphics will be buying the game, and they won't be able to do much of anything with it. One of the key failures will be cursor movement that is very slow. The practical minimum is AMD's Radeon HD 5570, according to the benchmarks performed by Toms Hardware.

Okay so I tryed tht but it still lagging alot do have any other suggestion ????

It's a vsync thing. There are instructions on disabling it all over the place (google or search here for skyrim vsync). It seems you can either have mouse lag, or this: http://www.youtube.com/watch?v=KD23g62zDIw&feature=feedu
