此枚举描述了当 GPU 完成渲染到渲染目标时应该执行的操作。
当 GPU 完成渲染到渲染目标时，此设置指定应对渲染结果执行的操作。基于图块的 GPU 如果存储操作为 DontCare，可能会获得性能优势。例如，如果在渲染帧后不需要深度缓冲区内容，则此设置很有用。
请注意，并非所有平台都具有加载/存储操作，因此此设置在运行时可能会被忽略。通常，面向移动设备的图形 API（OpenGL ES、Metal）会利用这些设置。
如果您使用 RenderBufferLoadAction.DontCare，渲染可能会失败或产生伪像，因为深度纹理中未定义的像素会导致深度测试失败。您可以使用 LoadStoreActionDebugModeSettings 来突出显示未定义的像素。
| 存储 | 需要将 RenderBuffer 内容存储到 RAM。如果表面启用了 MSAA，则会存储未解析的表面。 |
| 解析 | 解析 MSAA 表面。 |
| StoreAndResolve | 解析 MSAA 表面，但也存储多采样版本。 |
| DontCare | 不需要 RenderBuffer 的内容，可以将其丢弃。基于图块的 GPU 将完全跳过写入表面内容，从而提高性能。 |
