I've connected noise texture node in my material and when I'm changing scale parameter, I hear that my graphic card starts work louder. So I suppose it's need more cooling - doing more operations. Am I right with my assumption that scale parameter in noise texture is affecting on performance? Of course, I know that other nodes has their effects (especially bump node) too, but I see difference with changing scale. Here's my material: enter image description here

    $\begingroup$ When you're changing settings on nodes, the render viewport is constantly updating and resampling the scene. The Detail slider does have an effect on how efficient the node is. $\endgroup$ Aug 26, 2022 at 20:20
  • $\begingroup$ @AllenSimpson so the scale slider does no have an effect on how efficient the node is? $\endgroup$ Aug 26, 2022 at 20:26
  • $\begingroup$ It may, but I've never heard anything definitive on it. Probably negligible if anything. $\endgroup$ Aug 26, 2022 at 20:27
  • $\begingroup$ @AllenSimpson can you give me a hint where I can find more about it? Documentation has no answer to my question( $\endgroup$ Aug 26, 2022 at 20:34

    $\begingroup$ Generally speaking, and just looking at the node alone: No, not really. Only when changing a value, computing power is used. However, it always depends very much on what else you do with these values, so it always depends on your setup. $\endgroup$
