Direct Input

Hi all,
I'm in the process of writing my first game in VB and I'm using Direct X. Its a very simple shooting game for a school project. The game runs well so far but I notice a marked slow down when you repeadedly press the mouse buttons quickly. I am not using Direct Input now, would using that improve performance? I have an a loop that delays for a certain time running DoEvents, if I use DirectInput would I still have to use DoEvents in my pause loop?

Thanks in advance.

I'm not sure about the DoEvents, but DInput won't slow down the project anymore. If you need you can download a mouse demo from my website.

I really would like to know if Direct Input would speed up the game. It slows down a lot on the school computers right now.
