The drawspeed limit is 700 wpolies for official maps but epolies get to like 10 000+ in marine base. Only skulk teeth (those you see when you are skulk) add 954 epoly and when you are marine, your lmg adds 1680!
Are epolies somehow faster to draw than wpolies or is there some other reason why wpoly limit is so damn low? And if they are faster to draw is there a way to turn everything in my map to models which only add epoly?

Models can have more polies without hurting too much to the performance, but since the way HL has to light models is quite bad, turning everything into a model would look horrible.

thanks... Still I'm curious why dont models hurt performance so much. Are models more client side than wpolies or what? And why didnt valve make all polies use that less performance harming way?
EDIT
And yes I know Im asking stupid questions.

I think it has to do with the fact that the engine doesn't have to calculate collision hulls or lightmaps for model pollies.

No lightmaps and a simpler texture mapping system that doesn't require scaling and rotating the texture coordinates for every face (the skin image is already warped to fit the model's skin coordinates, so you don't need to do image transforms at runtime).
The engine also renders models as triangle strips since the textures are usually continuous across at least some of the faces -- that's much faster than having to start over for every triangle.
Models using the new transparent model code will have more of an impact per epoly.
