Panda3D under Vista 64-bit?

I want to upgrade from WinXP 32-bit to Vista 64-bit. Does someone use Panda under 64-bit operating system? What are your impressions (does it actually work? work faster/slower compared to 32-bit OS? and so on).

it works in 32 bit mode on a 64 bit windows i think. So you should not notice a difference.
