Hi. I tested prop. with DirectX9, whole cockpit view is black, and a yellow prop. tip circle show, I installed DirectX11 back. Odd thing is, only this plane has weird prop. disk.
if you can move to P3Dv4 - it is 64 bit and runs at high FPS, the downside is that you need to buy some add ons again like the A2A Mustang and Spitfire.
