By default, all camerasA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info

Follow these steps:
Use the Mipmap Bias setting in a Streaming Controller component to force Unity to load smaller or larger mipmap levels than the ones mipmap streaming automatically chooses.
Unity adds the Mipmap Bias value to mipmap levels from textures in the camera view. For example, if you set Mipmap Bias to 2 and mipmap streaming chooses mipmap level 1 for a texture, Unity loads mipmap level 3 (1 + 2).
You can also use the StreamingController.streamingMipmapBias API to control this setting.
To set the maximum GPU memory that Unity uses for textures, follow these steps:
The memory budget is for both mipmap streaming, and all the mipmap levels of textures that don’t use mipmap streaming. For example, if you set Memory Budget to 100 MB, and you have 90 MB of textures that don’t use mipmap streaming, the memory budget for mipmap streaming is 10 MB.
To avoid exceeding the memory budget, Unity does the following:
You can use the Max Level Reduction property to stop Unity removing mipmap levels smaller than a certain level. This value is also the mipmap level Unity loads at first startup. For example, if you set Max Level Reduction to 2, Unity loads only mipmap levels at level 2 and larger, and keeps them in memory.
Unity must keep mipmap levels above the Max Level Reduction value in GPU memory. This might mean Unity exceeds the memory budget.
To estimate a memory budget for your project, follow these steps:
This lets you make sure Unity has enough texture memory available for the most resource-intensive areas of your scene, and prevent textures from dropping to a lower resolution. If you have extra memory available, you can set a larger memory budget so that Unity can keep texture data that’s not visible in your scene in a GPU cache.
Note: If you use Texture.desiredTextureMemory
in the Editor, the total size might include textures Unity uses to render Editor windows.
You can use the following APIs to set and control the memory budget at runtime:
