Thank you DarkWraith,
It was the other way around for me. I was using nvidea many years ago until I had some annoying issues with their older cards. So, I switched to ATI because a large percentage of lads from my IL2 squadron were at the time using ATI without any issues at all.
Your reply prompted me to try something which I neglected to do initially. I opened the ATI software and disabled the Crossfire, so now for this game only I'm using only one video card. I'm pleased to report that I now have exterior views. Issue solved. Thanks again old chap!
All I have to do now is learn how to drive the boat.
Regards
War
