Unity 3D Developer Interview Question:

Do you know what Is Fixed Timestep In Unity3d? Why Does Fixed Timestep Setting Affect Game Speed?

Submitted by: Muhammad

Fixed Timestep feature helps to set the system updates at fixed time interval. A queue like mechanism will manage all real-time events that are accumulated between time epochs. If frame-rate drops below some threshold limit set for fixed timestep, then it can affect the game speed.
