About the only real thing I have a problem with in Carrara is the time it takes to load and save a file.  It takes several minutes even for a relatively standard file (100 MB is about the normal size files I generate.  If that's larger than most folks, let me know).
Does it make a difference where I keep my Poser runtime folders?  I have Carrara on my C drive but all my Poser runtimes are on a separate (internal) hard drive.  Would loading and saving be significantly faster if they were all on the same drive?
I'm running Windows Vista Ultimate 64-bit, quad processor, 6gb ram.
Thanks!
