Hi

I think you have something more basic then you Poser setup going on here.

My system is 2 years old and I get almost instantaneous refresh even with my setting at almost max, I even have texture res set to 4096.

The only thing I turn off is antialiasing.

I use Scene Window same as aRIBee.

Make sure your video drivers, memory config and things like that are all up to date.

Run CCleaner and defrag, (it can't hurt), I use Defraggler because you can just defrag files without doing the whole drive.  It makes a noticable difference and I do it almost every day. 

I don't have any real idea what's going on but I think something in you computer isn't quite right some place, I guess I can't be less specific then that.

Are you a gamer?  Do you get high frame rates in games?

If you shoot a mime, do you need a silencer?
