You can control the playback speed of your simulation using the playback controls. The playback control setting allows you to choose between three different playback modes. The first is the default value of "Fastest Possible". In this mode the simulation will play back as fast is it possibly can, with no delays between the simulation steps. However, if you simulation is simple enough then it may playback so fast that you cannot see what is going on. In that case you will need to use one of the other two settings. The second setting is "Match Physics Step." This setting will attempt to get the simulation to playback in real time. It will add a delay to the end of each time step to make up the difference between the real time for that step, and what was actually used by the simulation. So for example, lets say you set a physics time step of 0.4 ms, and the simulation engine only used 0.1 ms. It would add a sleep for the remaining 0.3 ms to try and make the total step time 0.4 ms. The third settings can be used if you want to slow the playback down even more. It is "Use Preset Value." When you select this then a new property called "Playback Time Step" is shown where you can enter the time that you want added to each step of the physics engine. In the previous example 0.3 ms was added to the time step to try and make it match real time. With this option you can specify how long you want that period to be.
Playback Speed Control
Frame Rate
Sets the frame rate for the simulation windows.
Default value: 30 fps
