The purpose of this sample is measuring FPS, memory consumption and how these values are changed depending on avatars number on the scene.

The following indicators are mesured:

Avatar Count: number of avatars on the scene.
FPS: FPS of the latest frame (1.0f / time_between_updates_in_seonds).
Avg FPS: average FPS.
Total Used Memory: memory used by an application right now. Available in Unity 2020.2 or above.
System Used Memory: how much memory is taken from the system. Includes allocation pools, extra headers and memory required for code and data. Available in Unity 2020.2 or above.
Texture Memory: memory is taken by textures. Available in Unity 2020.2 or above.
Mesh Memory: memory is taken by meshes. Available in Unity 2020.2 or above.

If you need to reduce memory consumption and increase FPS in your application, we recommend modifying these parameters:

Texture Size: you can specify texture size for body, outfits and haircuts.
Using PBR textures: there are additional (PBR) textures for body and outfits. Try to disable them if textures take too much memory.
LOD: there are several LODs for body mesh. Also you can use lowpoly outfits.
Blendshapes: blendshapes increase mesh size. Don't generate them if they are not used in your application.
Generated Haircut Parameters: it is possible to specify number of triangles for the generated haircut and its texture size.
