I am trying to make a necklace chain with physics. However, if I scale, lets say 3 chains, to smaller size then run simulation. It always lags my systems to the point that windows 10 says the program is not responding and greys out. If I scale it back to a much larger size than my CC3 character, it runs a lot better. Does anyone experience this issue? I am running on I7 8700 CPU with 1080 ti and 48 GHz of ram.

Thank you
