x6 How to stop background from changing from white to black when orbiting camera?

You are correct! I hadn't optimized my Nvidia 675 to CA 6. Thank you. Cheers!

Hello,

I just downloaded Chief Architect yesterday for the first time, so I am a new user. I downloaded X6 and I do not have that issue at all... been using it for a few hours now. I would guess that it may be lack RAM or graphic card memory/CPU power. I could be totally wrong, but it just sounds like the computer can't process it all while it moves. I've got a pretty dang powerful computer, so am guessing why I've never seen this. Again, just my thoughts.
