HI

遇到了一些GPUScene更新的卡顿问题。

GGPUSceneParallelUpdate在5.1中默认没有开启的，想问下这是基于什么原因 ？ 在PC上默认开启会有哪些已知风险？

Hi,

我没有看到这个功能有什么已知的风险，在最新的5.7版本中，默认已经打开了，可以参考 [https://github.com/EpicGames/UnrealEngine/commit/e3b36804bbf1b993cddcff34c93134d9119fecec](https://github.com/EpicGames/UnrealEngine/commit/e3b36804bbf1b993cddcff34c93134d9119fecec)
