I updated the video card driver already, but still the same,
currently I am using windows 64bit , before I was using 32 bit(not problem at all) the problem is with 32 bit the windows shows only up to 3GB ram, I am using 6 gb ram, so I decide move on to 64 bit for the ram, I am really confused between the windows, do you think is that windows problem?

what I did so far:
1- near clip camera has been changed to higher value
2-video card has been updated
3-the scene is not really heavy
4-enough ram to support the scene.
5-using windows xp 64 bit wit maya 64 bit as well
any help guys?
