Help Performance issues

Hi,

The number of ropes in your scene is pretty much meaningless, what determines performance is the amount of particles and the amount of iterations spent in the physics simulation.

You could have 200 ropes made of 5 particles each, or a single rope made of 1000 particles and performance would be the same. For reference, take a look at our performance measurements:

Edit:
Made a quick test scene with 50 one meter ropes, 10 particles each, using the line renderer and default solver/Unity settings. Getting roughly 80 fps in editor and +250 fps in standalone. Video:

Is there any chance you can send me that scene? I cannot seem to get that performance with my version of Unity 2018.3.2f1. I have had GC issues with other things too, which makes me believe it's maybe the version of Unity acting weird. With your scene I could test that theory.

To answer "StudioTatsu", I highly doubt it's my machine but here are my specs:

CPU : I7 7700K
GPU : 1080 GTX TI Strix
RAM : 32 GB Corsair 3000 mhz
