2016版顶配macbookpro-touchbar版本，随便开个空场景，编编UI，改改地形风扇就已经飙的飞起了，都不知道它在干嘛。。。。热的心好塞啊。。。。

另外如果输入法没切换到英文，以中文输入法输入英文，会导致频繁崩溃。。。新建个地形，灯光忽明忽暗。。都是什么情况啊。。。

输入法这个是挺容易出问题……至于你说的忽明忽暗……你确定不是眼球自适应的问题？

就顶配的白苹果而言，性能还是很弱，特别是笔记本。  
我在去年装了台黑苹果，用的是E5 + TitanX，由于编辑器尚不支持macOS下的metal，所以效能很低，但是打包ios是可以支持的。  
作为对比，同样的硬件基础上，发现UE4 editor在开了vulkan的Linux环境下图形效率比MacOS下高很多，不过编辑器需要自己编译。可以参见此文： [A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums](https://wiki.unrealengine.com/Vulkan)

额，自然可以确认不是眼球的适应问题，很明显的，转动视角，停住，然后由亮变暗大概2到3秒的过程

我只是在想，在没有使用UE那些高级渲染功能的时候，场景内也没什么东西，为什么会消耗这么大，虽然unity和ue4的效果没法比，不过开unity基本完全不会发热

那……就基本上可以确定是眼球自适应的问题。你在Postprocess setting里面把眼球自适应关掉再看看？

其实……区别还是挺大的…… 默认使用的Deferred rendering导致就算没有东西，也会有五张Gbuffer的带宽和显存占用，更别说默认开启的各种Post process效果了……

你可以设置下系统电源管理，貌似ue开起来会大量吃cpu，这个可以从系统上面设置。

编辑器预览全调Low，或者使用Default Mobile预览模式，新建工程时选择面向移动开发，图像质量最低

其实我主要纠结的并不是怎么以低质量去提高效率，而是在最基本的没什么东西的场景内，做一些简单的操作，是否真的要计算那么多东西，是不是有很多地方可以优化，如果有是否官方有排入改进日程

关于改进的计划，可以看官方的 Roadmap [Trello](https://trello.com/b/TTAVI7Ny/ue4-roadmap) 在这里可以看到后续引擎要添加的新功能的规划。 如果清单中没有也可以在 Feedback 这里发帖子说明一下。 [https://forums.unrealengine.com/forumdisplay.php?24-Feedback-for-Epic](https://forums.unrealengine.com/forumdisplay.php?24-Feedback-for-Epic)

就我个人使用苹果笔记本的经验来看，在出现外挂显卡之前，苹果内置的显卡运算能力其实算不上很强，对于 VR 这类需要高负载的来说还是比较吃紧的。 在这里可以看到文档中对于苹果硬件的需求表 [硬件和软件规格 | 虚幻引擎文档](https://docs.unrealengine.com/latest/CHN/GettingStarted/RecommendedSpecifications/index.html)

如果是Win10 或者win7 你笔记本上有图形和集成两个显卡的时候 可以强制设置 UE4editor 这个程序走集成显卡. 这样虽然慢点. 但是静止状态风扇不会太吵.
