Answer 1

I ended up using InteropBitmap, it is the fatest bitmap rendering class from WPF.

It allows you to map the image that you want to paint (in memory) and then reder it as a Image. This was perfect as i needed to plot points on the screen.

I got great performance (almost 50Hz for 20k points), i also use PLINQ to update the points in memory.

Try and read about ZoomableCanvas. I believe it can solve your problem. You can render all the points as small rectangles/ellipses inside the ZoomableCanvas.
