Mouse Move Performance

Jan 10, 2014 at 12:42 PM
I am trying to improve the speed of my viewport (containing around 100 models) and I cannot figure out why the processor spikes when I am moving the mouse over the viewport.

I would like to be able to add more 3D models to my viewport and I am looking for a way of reducing the CPU load. Is there some functionality which can be "sacrificed" to get better performance?

WPF might be doing hit-testing while you move the mouse. There is some way to disable this, and then only do hist testing when you need to, or on a timer. See:
