Photoshop cs5 extended 3d issue

Question

Hi,
i made a selection then i made it into a 3d layer with reproussé and then turn it into a 3d object , this part works all fine
but as soon as i accept the changes i make, and start to use the 3d rotation tool and start rotate it. my background goes transparent while dragging/rotating my object . this is very enoying coz i cannot see my background while doing this.. anyone has the same problem and or a solution to it?
i checked photoshop preferences ( CTRL + K  ... performance) and played with the settings. nothing usefull. also i updated my system to the latest video drivers. everything runs smooth even photoshop.
my hardware specs are pretty decent im sure it isnt that, although i could enable or check something somewhere , who can help me about this issue...

Generally good advice is to check with nVidia on their web site and see if they have released any recent video drivers that fix the problem you're seeing.
