Transparent/Cutout/Diffuse draws 8x faster than Diffuse??

Unity Engine

I’m new to shaders, so this is a little confusing. I made a test scene with 52 of a particular mesh. With a Diffuse shader on the material, they rendered at 8 FPS. With a Transparent/Cutout/Diffuse shader on the material, they rendered at 64 FPS. Can someone explain this to me, a shader newbie? More importantly, will my meshes look “worse” in some scenarios? (They look the same to me.)

I got similar results with Specular vs. Transparent/Cutout/Specular, except the speed benefit was only double – Specular = 20 FPS, and Transparent/Cutout/Specular = 41 FPS.

Without looking at things, or duplicating your test scene…I will guess it is shadows.

If that isn’t the case, sorry. Shadowing would be the first thing I would look at.

Any idea if these new shaders will look “worse” in some way? They seem to look the same.

you can download the builtin shader sources in the resource section on the website and compare them to see where the cutout goes a different way and potentially omits something you need
