大量物理的创建跟销毁会导致游戏的卡顿，帮忙看下有没有比较好的优化方案。

你好，5.6针对level streaming加入了组件增量注册，异步物理，时间预算等方式解决卡顿，但如果一个ISM上的实例过多导致单个组件的物理注册过于昂贵，可以根据项目需求看是否可以通过禁用物理碰撞，或者将一个大的ISM拆成更小的部分来解决(比如InstancedFoliageGridSize)

另外目前虚幻社区也针对level streaming的卡顿更新了相关文档，感兴趣也可以参考一下:[link](https://dev.epicgames.com/community/learning/tutorials/qpll/unreal-engine-level-streaming-hitching-guide)
