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.
Contents
Background
LOD
Main article: 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.
c_models

- 0-8000
- Key
- Unoptimized

Notes
- Medi Gun and c_models
- The Medi Gun equipped on its own uses w_models and v_models. But when the Kritzkrieg attachment model is applied, a c_model variation of the Medi Gun is used.
- Unused c_model content
- Fire Axe, Revolver, Scattergun, Syringe Gun, Wrench, Stickybomb Launcher, Bat and Bonesaw.

- Note: the chart scale is not the same as the previous lists! You can not compare the lengths of the bars in this table with bars in the other tables. You CAN compare the numbers though.
