Every object drawn within sight of you and anyone else in the area has an effect on your frame rate.
Houses, barns, trees are all designed to give the landscape "clutter" without effecting frame rates any more than absolutely necessary. However, once you start dropping tank hulls and plane parts around the landscape, you will instantly start effecting frame rates. Now many of us have enough overhead that we could afford to lose 10-20%.
But there are many who fly who are right at the borderline already, or even below the mid 30's it takes to fly effectively.
Impact their Frame rates 20% and you have in effect shut them out of the game.
Hitechcreations does the best it can do to give a level playing field to all its customers.
What your asking for would change that.
Would it be nice, sure, but its eye candy. Get past the eye candy and get into the combat.
