Texture sampler in shader graph vertex shader kills performance

[jordbugg]

I’m getting big performance drops using texture samplers in the vertex shader in shader graph on mobile (Android).

Minimal example:

Connecting the texture to the multiply brings fps in my mobile build from 50 to 45. It’s a single material instance in the scene using this shader. The texture in the example is a low res black square.
