I know people use programs like speederxp which speeds up your computer for games likes cs. The website for that is http://vr.mmosite.com/
Not sure if thats what your looking for.

 

speed xp xploits mechanics in your pc and allows you to run faster in online (fps/mmo) games.

 

I just wanted to know what they DID, as in if i use it will it possibly harm my comp or just increase temps or both?

 

I know for a program like speederxp you can do things a lot faster. ex. Build buildings faster, Move faster ...
Not sure if thats the program you were talking about.
Also i dont know if it does any harm
