PBR materials vs. Textures

I have a game that’s reliant on custom textures, and I’m wondering about the difference in performance between textures/decals and PBR materials. I’ve looked around the dev forum and I’ve heard that textures can be bad on performance depending how you use them, however I couldn’t find anything about comparing the two.

I assumed that textures are more performant, because textures are rendered as well as the material its being applied to. However, I’m not sure how it completely works and I could be talking nonsense.

PBR materials(which usually use 4 different images) generally are worse for performance, but it isn’t a big enough hit for you to really be concerned. Just make sure to utilize the material service if you’re using the same material all over the place
