*If large amounts of text (especially using true type fonts) are displayed, the frame rate might be significantly reduced.
*You might try to modify clipping variables, or attempt to 'hack' in your own mutable clipping procedures.
*If using A6, you might try to use simple WED geometry, and attempt to design levels carefully for faster frame rates.
*However, perhaps, you should not assume entities are clipped just because they are unseen.
Entities might be clipped in only the following two instances??? (corrections requested):
*entity is behind camera
*entity is outside viewable range, as defined by...
see (custom clip procedures) & David Lancaster & level loading systems?
see area & grid pre-compiled clipping systems?

'I' had an integrated Intel Accelerated Graphics piece of sh!t, and at least 100 actors in a level, in a near space, doing various activities at a fps that did not often waver below 15.
Of course, that was with A6, but A7 should not be slower

(maybe with Lite-C it is?).

It is seemingly more reasonable to match conflict / aggression with the same, when ridiculously over-armed.
Why not ask George? He seems to be a friendly, knowledgeable, hard-working, highly-functional, helpful individual.
Too late now, maybe.
Where's that link to frame rate tips?
Anyone?
Too lazy (& busy) to locate it, today.
