Is this surface shader too heavy for mobile?
I am having problems with thermal throttling on my Samsung S8+ (It is tt for sure cause when i cool the device i don't have fps drop). I am using Beautify PP and default anti-aliasing. Rendering of the scene takes between 70-80 draw-calls where :
- 1 Clear
- ~50 Scene objects
- 12 UI
- 15 Post-Processing
- 1 AA
I am using bellow shader on every object except on shadow plane where i use unlit-transparent and glass transparent surface shader(I have 1 shadowplane with texture and 2 planes for glass). No shadows in the scene and only 1 directional light. I baked shadows and put it on a plane as a texture.
Scene has 27k triangles in total (38k verts), using 3 instances of the mentioned shader 1 for the floor, 1 for the bottom part of the box and 1 for the top part. Scene is rendered in 1080p resolution. Instancing is enabled and all materials use 2048 textures. I hope someone can help :)

o.Metallic = _Metallic1 * comb.r + _Metallic2 * difference;

o.Normal = normals;
o.Occlusion = occlusion;
o.Alpha = comb.a;

FallBack "Diffuse"
}
I made it this way cause all my objects r made from like 2 types of material, lets say matte black and gold so i use 1 texture for that, better than using 1 for albedo and other for metallness, occlusion etc.
