Laggy Mouse movement?

Is it just me, or is there a delayed mouse movement? kinda laggy like; does anyone know if theres a way to fix this?

Yes, you have to go into prefernces.txt Look for ouse scrool speed (or something like that) change it to whatever you want. Im at about 6 or so, and it run very smooth. PM if you have anymore question about it.

Cheers!
