使用 Affectiva 的 Unity 插件时 iOS 设备出现抖动

Question

标题基本上说明了一切，我正在尝试运行一个非常基本的 Unity 游戏，它使用 Affectiva 的 Unity 情感 SDK 捕捉 2 种情感。该游戏甚至在低端 Android 设备上都非常流畅，但在 iOS 设备上就不是那么流畅了（目前在 iPhone 6 - iOS 10、6s - [=14 上测试=] 11, 7).我在我的游戏场景中将检测器和相机输入脚本附加到主相机，采样率设置为 8，目标宽度为 320，目标高度为 240。但无论怎样游戏都不运行流畅。一旦我禁用这 2 个脚本，游戏就会在 iOS 上顺利地运行开始。有什么改进游戏性能的建议吗？

Answer 1

有一项未发布的更改可以提高性能。你能试试这个改变，看看它是否有帮助：
