ArcScene - certain features disappear during animation

[LenDesson]

While playing an animation, I am experiencing some 3D Features (buildings) disappearing and reappearing.
I thought it might have to do with the view angle, but after adjusting that and re-recording the animation, I am still seeing the same behavior.
Thoughts?

I have also seen this before, not during an animation but just in ArcScene. I believe its just down to the graphics memory. Need to beef this up. Maybe a new fancy card?
Perhaps someone else has a better fix!
Cheers,

Certainly possible it's a resource issue, however I reduced the strain on the card by turning off pretty much every other layer in the scene and it still does the disappear / reappear behavior.
