This my fix of this very good mod
 Mass Effect Mouse Fix? - which the removes mouse acceleration...

(but at the same time makes the mouse sensitivity pretty low with the 100% slider in the game menu)

If you need MORE SENSITIVITY in your MOUSE after Mass Effect Mouse Fix ...

You need EDIT 3 FILES -
"...GuiResources.ini" in this path:


   x:\GAMES\Mass Effect\data\config1                                           - file 1 ("DefaultGuiResources.ini")
   x:\GAMES\Mass Effect\data\config2                                            - file 2 ("DefaultGuiResources.ini")
x:\Users\user\Documents\BioWare\Mass Effect\Config         - file 3 ("BIOGuiResources.ini")

 
Find (Ctrl+F) and edit this line "MaxMouseSense=11" to "MaxMouseSense=33"  (example "33")



"These actions expand the range of Mouse Sensitivity within from 0 to 100% !!!
Now You can change the sensitivity what you want as usual from the game menu"
