Poly Counts

I am currently trying to make an environment I modelled for a class project compatable for Uru. Unfortunately, as it was just modelling, we were required to model alot of detail (which could otherwise be simulated through texturing). As a result, the environment has a high poly count. So I was just wondering if there's any particular number range I should be aiming for when it comes to overall age poly counts in Uru? I want to find a good balance between performance and detail if possible. My current overall environment poly count is about 90,000 faces, thought this can come down more since there's still some extra stuff I'm gonna remove. However I am hoping to expand on the environment I have to make it larger. Can anyone give some useful pointers for handling overall poly counts in Uru to maximise performance while not having to do away with too much detail?
Thanks!
Thanks!
