Quality Settings 的脚本接口。
可以有任意数量的品质设置。在项目的 Quality Settings 中设置每项品质设置的 详细信息。在运行时， 可以使用该类更改当前品质级别。
| activeColorSpace | 活动颜色空间（只读）。 |
| anisotropicFiltering | 全局各向异性过滤模式。 |
| antiAliasing | Choose the level of Multi-Sample Anti-aliasing (MSAA) that the GPU performs. |
| asyncUploadBufferSize | 异步纹理和网格数据上传可在渲染线程上以基于时间片的方式异步上传纹理和网格数据，同时对内存和时间切片进行严格的控制。除了驱动程序必须进行的分配以外，不进行任何其他分配。为了读取数据和上传纹理及网格数据，Unity 将重用一个大小可控的环形缓冲区。Use asyncUploadBufferSize to set the buffer size for asynchronous texture and mesh data uploads. The minimum value is 2 megabytes and the maximum value is 2047 megabytes. The buffer resizes automatically to fit the largest texture currently loading. To avoid a buffer resize (which can use extra system resources) set this value to the size of the largest texture in the Scene. If you have issues with excessive memory usage, you may need to reduce the value of this buffer or disable asyncUploadPersistentBuffer. Memory fragmentation can occur if you choose the latter option. |
| asyncUploadPersistentBuffer | 此标志控制在没有活动加载操作的情况下是否仍然分配异步上传管线的环形缓冲区。 要在所有上传操作完成后保持环缓冲区分配，请将其设置为 true。 如果遇到内存使用过多的问题，可以将其设置为 false。这意味着可以减少运行时内存占用，但可能会出现内存碎片。 默认值为 true。 |
| asyncUploadTimeSlice | 异步纹理上传可在渲染线程上以基于时间片的方式异步上传纹理，同时对内存和时间切片进行严格的控制。除了驱动程序必须进行的分配以外，不进行任何其他分配。为了读取数据和上传纹理数据，将重用一个大小可控的环形缓冲区。使用 asyncUploadTimeSlice 设置每帧的 异步纹理上传时间片（以毫秒为单位）。最小值为 1，最大值为 33。 |
