Well for a start, you're going to be creating loads of geometry. Are
you rendering your drawings to bitmaps at all? Sounds like a
performance issue to me. Drawing vector lines takes CPU - this is just
a fact of life.
What I'd recommend is something along these lines:
User presses mouse
User draws with pen tool
User releases mouse
The line drawn is drawn to a bitmap
Repeat.
Does this make sense?
It may not solve your immediate issue with the webcam, but you will
definitely run into it sooner or later.
Hope this helps,
