Simulation time is not stable

[onurg57]

When running simulation in normal speed, Simulation time running at 0.6x and suddenly it become 4-5x and decrease again. While video capturing it works normal. Even while working with void controller.

This really depends on the simulation setup, including the controller program. It may be possible that at some steps the simulation runs computer intensive tasks, such as the rendering of a high resolution sensor. Running video capturing will slow down everything and may make the simulation run more steadily. Note: you could use the "run-realtime" mode to ensure the simulation speed won't exceed approximately 1x.
