Physical UI Help

Hey guys. I’m planning on making a custom UI using parts instead of GUI elements, but I’m worried it will lag, since I want to move it by moving it to the cframe of the player’s camera by using RenderStepped. Will this lag my game? If so, what is a better way to achieve this? I would like to avoid using ViewportFrames since I would like to use particles and neon parts in my UI.

Depends on how many parts and how detailed they are. Render Stepped on its own causes 0 lag it’s when you start looping over large amounts of parts when it would start to lag
