In order to get Mouse Sensitivity to be equal on both the Y and X axis without a "hooked" vorbisFile.dll, you must first know how it works.
If you put your sensitivity on 1 the X axis will be at it's slowest sensitivity and the Y axis will be at it's fastest sensitivity.
If you put your sensitivity on 16 the Y axis will be at it's slowest sensitivity and the X axis will be at it's fastest sensitivity.
So what to do?
Set it at the middle (8 bars) and your X and Y axis will be equal in sensitivity.
I myself play with that 8 sensitivity in-game and I have a Logitech G500 which is set on 500 DPI for GTA SA and I seriously have no problems....
Btw, SA isn't Call of Duty or Counter-Strike so you don't really need a lot of precision....
