Model vs. performance

[mathuzzz]

So I was trying to finish my little campaign and as I hated design of some of the original Warcraft 3 models, I replaced them with different ones, which have usually larger polycount, complicated animations, more textures, etc.... I would like to ask what should I look for to keep game performance clean? What is the largest FPS eater? Is it the actual size of the model, or number of vertices, or? Thanks in advance.

Models themselves don't seem to cause that much lag, if any at all. What causes lag is leaky triggers, lots of spells going off at once and masses of doodads on the screen at the same time.

If you spam a... TONN of particles it may cause lags.
