Experimentation results.

For some reason, having a bunch of entities causes the engine's frame rate to drop quite drastically, even with 16x16 skins, 4 polygons and a small overall size (physical dimensions). I feel as if this is a bug so that's why I posted it here. With 2048x1024 skins, low poly, and small or large physical size, there is little difference in the frame rate. High poly, as expected, would drop the frame rate and the skin size has little effect on it.

The reason for my video card being seemingly as bad as my old one is because of this high entity count problem. I'm going to need like 1500 entities per world (likely more especially with the indoor worlds) plus likely another 500 for the main levels and this could mean running at 6 fps....
