Finally I got it. you have right many models (ebps ) much more requirements for the graphics. I have test my work on an ATI 3870 and an 3850. With first accelerator I did not face so many problems but with the second I have to lower the effects and textures from ultra to high to have a no CTD game. Thank you and Luciferum with the solution about atrib.sga and ww2 art.sga files ,no I 'm capable to continue and my work are safe and probable when everything test out I will release it .
