Never used proxy mate, have been looking at it but a lot of the people I talk to dont like or use it.
I have Maya 8 (oldy) and dont have smooth preview (its there but doesnt work on my version). I basically have to 'Alt ~' to get the quick preview and either convert back to poly or CTRL z.
Lately it has previewed ok BUT when I look at it, some components get 'stuck' in sub-d. I end up with 2 meshes (one usually wireframe- the sub-d). I cant delete it as it deletes the poly mesh too. They are connected somehow, I think its just my vid card (Nvidia 9600M GT).
I have had nothing but trouble with it, my games dont play properly either (high end ones, in particular GRAW2). Im a Bigpond Gamearena member and spent MANY many hours posting etc to find Nvidia has inherent problems.
One of the many quirks I face with software, Im used to it, my Surveying software is the same.
