I'm afraid I don't remember if texture filtering was off or on but I'm sure I got a message that Poser did not have enough memory to render.   First I lowered the bucket size all the way down to 8 and when I still got the message then I checked the texture size.  I will occassionally get the same message in a complicated scene but lowering bucket size does the trick.  

Btw, I'm on Winxp and running the 32-bit PP2010.   Maybe the 64-bit has a better performance since most people on 64 would naturally have more RAM.
