A new system called Dynamic Simulation has been sitting on Dev-Branch for some time. In short: it's a tool that can be used to selectively control object and unit simulation based on player and enemy presence. Due to the nature of the system, it cannot be used everywhere on everything. Some scenarios might heavily profit from Dynamic Simulation, whereas some might not be able to use it at all.   The Dynamic Simulation is still in the testing and tuning stage. Its core functionality is done, along with the Eden Editor implementation. It is now being tested and tuned in real scenarios. To get more information about the system, how it works, how to set it up and how to properly use it, please refer to the documentation: HERE   We would gladly welcome constructive feedback, so please read the documentation, give it a try, and share your notes. If you can provide real use-cases of Dynamic Simulation (i.e. attaching a mission where you are trying to use it), it will greatly increase the overall feedback value.   Thanks, Bohemia Interactive, Team Mike
