public static float streamingMipmapsMemoryBudget ;

Description

The total amount of memory to be used by streaming and non-streaming textures.

Non-streaming textures will always be loaded at the largest mipmap level (even if that exceeds the budget). Streaming textures will pick the smallest mipmap level possible to try to hit the memory budget.
