Just to clarify the reason for asking, if all goes well I will be working on my first player character rig in the next couple weeks. However the poly size (triangles) is double that of the usual cod4 player. Also it doesnt have the 'level of detail' options. Typically there are 3. Each one 1/2 as complex as the previous. So if you are within X units you see the highest poly one. Beyond that you see the second highest one and so on.
Helps because far away objects dont need to have full resolution. You may notice this as 'popping' at certain distances when the model shifts from one LOD to another. However considering this is a game made in 2007, before even DX9 cards were commonplace, I dont know if the other two LOD models are needed. It will also depend on the complexity of the maps these days, which are often much better than the stock maps, as well as the weapon viewmodels. And certainly if its a big server like it is here.
