Streaming

This section contains settings related to resource streaming.本节包含与资源流有关的设置。

Streaming settings

流媒体设置

Render Budget	渲染预算值，该值根据加载/创建时间限制一帧中加载/创建的图形资源的数量。预算值以秒为单位。
Mode	要使用的流媒体模式： Async —异步流模式 Forced 一次强制加载每个帧所需的所有网格和/或纹理（例如，抓取帧序列，渲染节点预览，预热等）
Use Memory Limit	启用和禁用异步资源加载（网格和纹理流）的内存限制。在Meshes Memory Limit和Textures Memory Limit字段中指定了相应的内存限制。
Texture Cache Resolution	纹理缓存元素的分辨率。这些最小化的纹理副本将代替原始副本。

Preload at World LoadingPreload at World Loading#

Shaders	在启动时启用编译加载世界中使用的所有着色器的功能。注意每次加载世界时，此选项都会将所有着色器编译并加载到RAM，这会导致大量内存消耗。建议尽可能使用预先生成的着色器缓存。在这种情况下，根据需要将必要的着色器从缓存加载到RAM。

Memory UsageMemory Usage#

Meshes Memory Limit	网格的缓存内存限制，以总GPU内存的百分比表示。
Textures Memory Limit	纹理的缓存内存限制，以总GPU内存的百分比表示。

ResourcesResources#

Destroy Duration	资源清除间隔，以帧数为单位。

The settings below are available for OpenGL API only.以下设置仅适用于OpenGL API。

注意

这些参数应针对每种特定情况和配置进行仔细调整，因为它们很大程度上取决于所使用的硬件和驱动程序。

Async Buffer	Size of an intermediate buffer (between the CPU and new resource) used for mesh and texture streaming, in Mb. The size of this buffer must be equal to the size of the largest resource (mesh/texture), otherwise in case of a larger resource, the buffer will be resized causing a spike. 注意 Be aware, that the size of this intermediate buffer will be added to total memory consumption.Be aware, that the size of this intermediate buffer will be added to total memory consumption. Be aware, that the size of this intermediate buffer will be added to total memory consumption.用于网格和纹理流传输的中间缓冲区（在CPU和新资源之间）的大小，以Mb为单位。此缓冲区的大小必须等于最大资源的大小（网格/纹理），否则，在资源较大的情况下，将调整缓冲区的大小，从而导致峰值。注意 Be aware, that the size of this intermediate buffer will be added to total memory consumption.请注意，此中间缓冲区的大小将添加到总内存消耗中。
Async Buffer Indices	Size of an intermediate buffer, analogous to the Async Buffer above, used for mesh streaming (to store vertex indices of meshes), in Mb. 注意 Be aware, that the size of this intermediate buffer will be added to total memory consumption.Be aware, that the size of this intermediate buffer will be added to total memory consumption. Be aware, that the size of this intermediate buffer will be added to total memory consumption.类似于上面的Async Buffer的中间缓冲区的大小，以Mb为单位，用于网格流传输（存储网格的顶点索引）。注意 Be aware, that the size of this intermediate buffer will be added to total memory consumption.请注意，此中间缓冲区的大小将添加到总内存消耗中。
Async Buffer Synchronization	Enable buffer synchronization for transferring data from the streaming thread to the main one. When disabled, both async buffer and async buffer for indices are created anew each time. This reduces the number of buffer synchronizations but increases the number of memory allocations. 注意 Sometimes (depending on the hardware/driver used, e.g. when the main thread is affected by sychronization primitives in other threads) memory allocation may be faster than synchronizations, in such cases, when streaming becomes unacceptably slow, it is recommended to disable buffer synchronization.Sometimes (depending on the hardware/driver used, e.g. when the main thread is affected by sychronization primitives in other threads) memory allocation may be faster than synchronizations, in such cases, when streaming becomes unacceptably slow, it is recommended to disable buffer synchronization.
