1 QUESTION that needs answering

[colmustard]

I want to change the mouse lag threshold on the default.ini in the DX:IW folder. When i change it to 0 on the text it won't let me save the changes to the same file, my comp. makes me change the name. I really don't know much about it. All i know is that i would like to get this game started without lagg. So can somebody elaborate on what I'm supposed to do, so the game can run good on my well equipped system?
