I've been using Vue 8 infinite since it came out, but suddenly my render times have skyrocketed and I can't seemt to figure out why.  As usual, the renders are fine until they reach the foreground ecosystem (i.e, grasses, etc.).  For the most part I don't think I've changed the ecosystems much so I doubt it's because of new plants being used.  I mean, we're talking about grasses so they shouldn't be too difficult.  As for atmospheres, I've tried rendering the same scene with newer atmospheres I've started using more recently as well as older ones, and still the renders are ridiculous.  And what makes this most frustrating is that I usually use User settings for the final render, and this slowness is occurring when I use Ultra.  Should I uninstall and reinstall?  Will that help?....for the most part I've gone back to Vue 7. 

P.S.  I know I need a better computer for Vue, but I used to render at high settings just fine (took a long time, but I could handle it) so I don't see why this happened.
