Splines/Spline Meshes murdering my Framerate

Hey all,

I’m having some trouble with Splines inside of the Unreal Engine. Specifically, when I’m using Splines to procedurally generate some cables, they are absolutely killing my framerate.

To create the cables, I’ve essentially followed this YouTube tutorial: UE4 Tutorial: Add spline-meshes procedurally - YouTube

Here’s a Screenshot of my Blueprints, as well as a Screenshot of my Cable mesh (which hardly contains any geometry…)

So, as above - essentially it’s exactly the same as the YouTube tutorial.

However, despite the simplicity of the mesh, it’s absolutely murdering my Framerate, shown below…

Why are the Splines causing my framerate to plummet so severely? A 25 frame loss is absolutely crazy for some simple pipes!

Cheers,
Dan
