Hello,

I am simulating 3 quad-copters at low speed, I have noticed recently that the real time factor decreases during the simulation slowly during the first 4 hours of simulation. Finally it stabilize to around 0.55 all the time. However, I did not had this problem when the speed of the quadcopters where higher. Also the machine is extremely powerful, It has two xeon CPU with 8 cores each one.

Do you have any idea about the reason for this issue, Best regards,
