Yeah, when a gpu is involved it is often cheaper to process everything rather than check what meeds to be processed.

I don't know how egui or the OP's app works, but we aren't talking about costly intersections of arbitrary surfaces but the sending of vertex data (for the vertex shader) in an integer interval (of nodes). This isn't about half or 1/10, but about 1/1000th of the data.

That may not have been clear, but I am talking about drawing less nodes in any case, also when using egui.
