Help Performance issues

Ok, so the simulation takes 1.2 ms (ObiSolver.FixedUpdate) and rendering (ObiSolver.LateUpdate) 3.8 ms, right? (FixedUpdate.PhysicsFixedUpdate is Unity's physics)

That could be within normal ranges, I was under the impression that simulation alone was taking 4-7 ms.
I assume you're using the default Extruded renderer for the ropes, correct? Are you using smoothing?

Yes, currently the ObiSolver.FixedUpdate() seems to remain between 1.2-2.5ms. LateUpdate() between 3.5-6.0 ms.

I am using the Rope Extruded Renderer for both the rods and the ropes. Smoothing for rods and ropes is set to 1.

EDIT: Okay, reducing the smoothing to 0, it is now 3 times faster. It takes around 1-2 ms for the LateUpdate() now.
