discardDepth Should the depth buffer be discarded?

Description

Discards the contents of the RenderTexture.

On some platforms, it can be good for performance if you indicate when the current contents of a RenderTexture aren't needed any more. This can save copying it from one kind of memory to another when the texture is reused. Xbox 360 and many mobile GPUs benefit from this.

Both the colour buffer and depth buffer are discarded by default but either can be selected individually using the optional boolean parameters.
