Graphic problem with FM2015

Hi,
I hope it is the correct section to post. I have two ATI Radeon 5700 graphics cards working in Cross Fire. Can I play FM 2015 in Very High modality? I ask this because I do not understand what happens. If I set Very High, the field is widened and the graphics are of poor quality (as it appeared in the video presentation of Miles Jacobson). Conversely, if I set Very Low Modality, you can clearly see, however, that in less FM2014. Can anyone give me some advice, please? It also happens to someone else?

thanks

Uberto
