I was about to make an event system for my Input class, when I realized that Windows has that built in. If my program would benifit from event-driven input, should I bother with DirectInput? If DI is more accurate, then I will, but otherwise I don't see the need to.

How does DI manage to be more responsive than Windows... is it because there isn't an event system wrapping it up? If made my own (which is what I'm planning on doing, of course), would DI still be faster?

I've had some aweful experiences with floaty mice and laggy keyboard input, so I want to get it right this time.


edit: clarity

DirectInput puts hooks down near the driver level and gets immediate responses when input events occur. DirectInput has an event system too, apart from the Windows Messaging System. Look up buffered data.

My understanding is DInput bypasses windows and talks directly (or at least close to directly) with the hardware. I find windows input to be very floaty at low frame rates. DInput is much better about that.
