I have an ATI HD5770 video card. I have a problem with edges and verts flickering or disappearing when I rotate or pan the camera:

Now I know it's not my settings in 3ds max2012 because this issue doesn't come up on my laptop that uses an nvidia gpu. Also this didn't happen in 3ds max2011. I tried changing the driver to open gl in 3ds max but my shaders won't work and Nitrous doesn't work either.
Also I tried the default settings of the ATI drivers in the vision engine control center and this still happens.
Any help would be cool
Thanks
