Texture Swaping. Ideas to optimize?

Hi everyone,

I want to ask if there is any way to optimize Texture Swap on a mesh.
Swap a bigger sized texture cause some small but recognizable visual shutter at runtime.

Does anyone have an idea to optimize in anyway, to reduce visual shutter as much as possible?
(The idea to exchange the mesh with another texture is not really an option)

Sorry I’m new here and don’t know where to ask exactly in this forum.

Thank you and kind regards,
CAB
