Im not sure if it is my computer ( AMD 1.2 300mg ram 64Mg Radeon video card) but I notice If I make a large empty box and add 2-5 enimies the framerate generally is pretty good but slows down considerably as entities are added.
Now if I add 10 more rooms and 50 baddies the game studders pretty bad.

I have found that clipping the camera range makes a pretty good improvement.

Is clipping the camera a normal thing to add to prevent this?

I know this is a VERY basic question but I seem to have missed something in the tutorials.
