Using Start3D() outside of main loop

Are there any bad things that can happen if I use Start3D() OUTSIDE of the main loop?
For example, what is the difference between:
Code: Select all
Start3D();
repeat;
; do something
until endResult.l;
Stop3D();
VS
Code: Select all
repeat
Start3D();
;do something
Stop3D();
until endResult.l
I don't notice anything bad happening when I start and end outside of the main loop, but I really would like to know how the PB guru's do it.

what do you want to do?
Stop3D() needs to be called before FlipBuffers().
And FlipBuffers() is normally inside of a main-loop.

Well, I don't want to take a performance hit from having it start and stop within my main loop opposed to only calling it once before and after the loop.

It needs to be called for every frame, you just have to go with it.
The graphics API equivalent requires it.

Ah, alright.

Also, there is no real performance hit anyway as long as you only call it once per frame.

I dont want to use RenderWorld(), too ... because in my game this call needs
over 5ms up to open end.
