Problem for me is I gain quite a bit of FPS with DX10. Plus my water textures and VC shading looks a lot nicer. I'll just have to flip back and forth.

True. It can give a better look to the water, but I'm not sure whether I get any FPS improvement. Besides, turning it on or off requires a restart of FSX. And I'm slack! ;D
