Looked around a bit also, but indeed both the old pix (dx9) and the new one (dx11/12), don't support 10.

Don't shoot me, but it's either way probably a good idea to move from 10 to 11.

Thank you both - this has been bugging me (excuse the pun) for days.

Hearing Joe's explanation I was just about to ripe out the vectors and replace them with fixed size arrays, but enemy_image.reserve(20); worked a treat ? thank you!
