High CPU usage when doing camera orbit.

[Bram]

I tried mouse polling rate of 500Hz instead of 1000Hz, same issue. I will try again, with lower settings.

It will also try to run wings w vsync off, to see if that helps.

To really fix this problem, it would help if wings or wx could batch process a whole bunch of movements before continuing redrawing the ui.

In psuedo code:

Code:

While ( mouse move available )
    Read event
    Update mousepos
Update viewport
Draw viewport

In my own code, c and c++, I used sdl2 for io and the standard approach is to process all events until there are no more, and then update/draw a single frame.
