I have a 3D level of say 20x20 tiles which consists of say 1000 models (Mostly planes) so i guess the polly count would be around 3-4 thousand.
Should i;
1. build the whole level
2. draw only the surrounding say 8x8 area

If your answer is 2 then do i destroy the models that go out of range and create new ones or recycle them somehow?

Thanks in advance for your help

I would suggest you to recycle them as 20*20 shouldn't be too much for keeping them
I would hide them as soon as they leave your 8x8 area maybe using Manhattan distance to make the area round if you like...
If you don't need physic collision then you could just draw them ...you create only one object of every type, place one draw it ...place another draw it and so on ...so you would end up having the picture without the geometry behind it...
Also are you using InstanceObject( newobjID, objID ) already ?

Thanks janbo. Seeing as it will be just about all planes i might try to recycle them.
I am using CloneObject(). Is InstanceObject() more efficient?

Yes thats the purpose of this command(perfect for trees,streets and buildings ), beware it doesn't support everything like a normal object does: animations I think...
And you need to keep the original object.
