### Remarks

When in mobile graphics emulation mode, Unity issues warnings when a RenderTexture "restore" operation is performed. Restore happens when rendering into a texture, without clearing or discarding ([RenderTexture.DiscardContents](/engine/6000.7/script-reference/unityengine/rendertexture/discardcontents.md)) it first. This is a costly operation on many mobile GPUs and multi-GPU systems and best should be avoided.

However, if your rendering effect absolutely needs a RenderTexture restore, you can call this function to indicate that yes, a restore is expected, and Unity will not issue a warning here.
