Bill, I really wish the manual would say stuff like that.  What you said makes a lot sense from what I can understand, but it's also counter-intuitive.  Most people (myself included because I was lazy) would think that 100% should produce better results than 99% because "how is this working on the inside isn't a question" a lot of people start with. 

I'll be honest, until Nancy mentioned it, it was one of the few render settings I didn't tinker with.  I was looking to other places to try and find out the cause and it never occured to me to turn down the cache.  

I was making a bad assumption because in a lot of cases, lowering a cache tends to hurts results.  So at least I know now that this one setting probably needs to be a little bit in the middle because I don't want to run 2k samples all the time.

All this not knowing what's happening under the hood has really been killing me in using poser and was an obstacle.  So I'm grateful for learning more.  The other day in chat for example, someone finally helped me with my mat room problem (when even SM's tech support couldn't, I tried it once).  Turns out leaving that Poser Surface preview on was what was causing all the lag I was seeing.

I guess I'll just have to learn when to start turning things off or turn them down.

WARK!
