I’ve also asked before… Reason for me is that I simply don’t see the point in upgrading to a newer version of Vegas anymore, I’m actually stuck with V3 and except color correction that appeared in V4, there is nothing I really would need except more speed.
I would even consider downgrading to Movie Studio if they gave me a partial refund 😉

P.S.: I don’t think 64 bit drivers are a prerequisite for things such as rendering.
