We use Obi Rope to simulate a fire hose in our game. Simulation works great except for the performance. When the rope is active in the scene the games FPS drop from 150 to 60.
We use only one rope with one fixed and one dynamic end. The whole simulation is attached to a moving truck.
This is our configuration:
Rope Blueprint: Thickness: 0.2; Resolution: 1; Particles: 100
When profiling in Debug Build mode you can see that the Obi simulation makes up for nearly 50% of the processing time.

There are no noticeable changes in performance whether the car is moving or stationary or whether the end of the rope is picked up by the player. Performance also gets better when disabling the rope altogheter. We aren't modifying any rope properties via script except the ropes' length when it is picked up, which doesn't seem to have an impact on performance.
We are using Obi 5.6 but upgrading to the most recent version had no effect. Similar scenarios from the demo scenes perform great and with no problems (1000FPS and more) which is kinda strange as our settings doesn't seem to be that different from the example settings.
Am I missing something? Thanks in advance!
