> In its current iteration, console developers familiar with the tech tell us that the engine struggles with proper threading, which is very important on a multi-core platform like PlayStation 4. > This refers to the engine's ability to exploit multiple streams of instructions simultaneously. Given the relative lack of power in each of the PS4's CPU cores, this is crucial to obtaining smooth performance. We understand that there are also issues with garbage collection, which is responsible for moving data into and out of memory - something that can also lead to stuttering. When your game concept starts to increase in complexity the things Unity handles automatically may not be sufficient when resources are limited.
