Optimized Rocket launcher w_model.
When discussing model optimization, LODs are often brought up. This article shows the effect of LOD on polygon count in models. The charts show which models have received optimization updates in the form of LODs, and which models are still unoptimized.
Background
LOD
To reduce the number of polygons that need to be rendered in a scene, the Source Engine will render alternate lower-quality models as the distance between the model and camera increase. LOD models are not created dynamically by the engine; instead all the levels of lower-quality models must be included in the game files for LOD to be enabled.
