So sorry about the delayed response.
I felt that I had to research more what you guys kindly explained to me before
I can make a proper response.
As for the fps drop, judging by the sounds, the fps drops even when I am
looking at a wall, and not at them. Furthermore, the time consumption of the
BotAI, and the GFX stay the same whether I am looking at them or at a wall.

Subject: Re: [ioquake3] Several Bot Questions, but mainly Why does the
Game become Choppy in a 63 bots match?
Is the fps drop when all bots are onscreen or when you're in a corner of a
map not looking at them? At even 1000 tris per bot, that's quite a bit of
geometry when the Q3 renderer starts choking, fps-wise, at like 45k tris.

Question Five(s): When do the Bot's "Actions" get executed- or where? I am
