Unity Game Optimization - Third Edition

Static batching summary

Static batching is a powerful, but dangerous, tool. If we don't use it wisely, we can very easily inflict enormous performance losses because of memory consumption (potentially leading to application crashes) and rendering costs on our application. It also takes a good amount of manual tweaking and configuration to ensure that batches are being properly generated and that we aren't accidentally introducing any unintended side effects of using various Static flags. However, it does have a significant advantage in that it can be used on meshes of different shapes and enormous sizes, which dynamic batching cannot provide.
