Performance Profiler

章节:

A performance profiler displays performance data in a timeline. It reports how much time is spent per each frame for updating all aspects of your project: rendering nodes that are in view, updating their states, executing scripts with game logic, calculating physics, etc.性能分析器在时间轴上显示性能数据。它报告每帧花费多少时间来更新项目的各个方面：渲染可见的节点，更新其状态，使用游戏逻辑执行脚本，计算物理量等等。

With the profiler, you can:使用事件探查器，您可以：

Detect the bottlenecks of your application检测应用程序的瓶颈
Check if art assets optimization is required检查是否需要优化艺术品资产
Check if code optimization is required检查是否需要代码优化
Compare the profiling results before and after the changes比较更改前后的概要分析结果

Total	Total time in milliseconds taken to both calculate and render the current frame. This is the duration of the main loop in the application execution sequence. Total = Total CPU + Waiting GPU 计算和渲染当前帧所花费的总时间（以毫秒为单位）。这是应用程序执行顺序中的主循环的持续时间。 Total = Total CPU + Waiting GPU
Total CPU	Total time in milliseconds taken to prepare the current frame (including update, render, and swap). 准备当前帧（包括 update，render 和 swap ）花费的总时间（以毫秒为单位）。
Total GPU	Total time in milliseconds taken to render the current frame on the GPU. 注意 This counter may not work on some GPUs.This counter may not work on some GPUs. This counter may not work on some GPUs.在GPU上渲染当前帧所花费的总时间（以毫秒为单位）。注意 This counter may not work on some GPUs.此计数器可能在某些GPU上不起作用。
Update	Time taken to update application logic. This includes executing all steps in the *update()* function of the world script. It also includes the update of states of all nodes (for example, update of the skinned animation or of a particle system to spawn new particles). If the Update time is too high, it signals that you need to optimize the application logic executed each frame.If the Update time is too high, it signals that you need to optimize the application logic executed each frame. You may also need to decrease the number of objects in the world, as updating their states (spawn particles by the particle systems, play skinned mesh animation, etc.) increases the load.You may also need to decrease the number of objects in the world, as updating their states (spawn particles by the particle systems, play skinned mesh animation, etc.) increases the load. If the Update time is too high, it signals that you need to optimize the application logic executed each frame.You may also need to decrease the number of objects in the world, as updating their states (spawn particles by the particle systems, play skinned mesh animation, etc.) increases the load.更新应用程序逻辑所花费的时间。这包括在世界脚本的 *update（）* 功能中执行所有步骤。它还包括所有节点状态的更新（例如，更新蒙皮动画或更新粒子系统以生成新粒子）。 If the Update time is too high, it signals that you need to optimize the application logic executed each frame.如果更新时间太长，则表明您需要优化每个帧执行的应用程序逻辑。 You may also need to decrease the number of objects in the world, as updating their states (spawn particles by the particle systems, play skinned mesh animation, etc.) increases the load.您可能还需要减少世界上的对象数量，因为更新它们的状态（通过粒子系统生成粒子，播放蒙皮的网格动画等）会增加负担。
Render CPU	Time taken to prepare all data to be rendered in the current frame and feed rendering commands from the CPU to the GPU. If Render CPU time is too high, it signals that art assets may need to be optimized, for example: LOD system should be used;LOD system should be used; polygon count of models should be reduced.polygon count of models should be reduced. LOD system should be used;polygon count of models should be reduced.准备要在当前帧中渲染的所有数据并将渲染命令从CPU馈送到GPU所花费的时间。如果“渲染CPU”时间过长，则表示可能需要优化艺术品资源，例如： LOD system should be used;应当使用 LOD 系统； polygon count of models should be reduced.应该减少模型的多边形数量。
Waiting GPU	Time between completing all calculations on the CPU up to the moment when the GPU has finished rendering the frame. (See the illustration). This counter is useful to analyze the bottleneck in your application's performance. When Waiting GPU time is equal to 0, it signals that scripts take too long to be updated and calculations are too intensive for CPU to perform them fast enough. In this case, your application has a CPU bottleneck. Optimize your update block in the world scripts or reduce the number of objects updated each frame.When Waiting GPU time is equal to 0, it signals that scripts take too long to be updated and calculations are too intensive for CPU to perform them fast enough. In this case, your application has a CPU bottleneck. Optimize your update block in the world scripts or reduce the number of objects updated each frame. High Waiting GPU time means one of the following: low framerate signals that there exists a GPU bottleneck.

In this case, your application has a CPU bottleneck. Optimize your update block in the world scripts or reduce the number of objects updated each frame.等待GPU时间等于 0 时，它表示脚本花费的时间太长，无法更新，并且计算量太大，CPU无法快速执行它们。在这种情况下，您的应用程序会遇到CPU瓶颈。在世界脚本中优化您的更新块，或减少每帧更新的对象数。 High Waiting GPU time means one of the following: low framerate signals that there exists a GPU bottleneck.

Allocations Textures	Number of memory allocations for textures during the frame.帧期间纹理的内存分配数。
Compile Shaders	Number of shaders compiled during the frame.在帧期间编译的着色器的数量。
Dynamic Reflections	The number of dynamic reflections drawn per frame. In case of cubemap reflections, if all six faces are updated, six reflections are rendered each frame.每帧绘制的动态反射数。如果是立方体贴图反射，则如果更新了所有六个面，则每帧会渲染六个反射。
Lights	Number of light passes rendered per frame. This means that the counter displays the number of all light sources that are currently seen illuminating something in the viewport. This value also includes additional passes for rendering lights in the reflecting surfaces (if dynamical reflections are used). Plain 2D reflection will multiply the number of rendering passes by two, while cubemap-based reflection with six faces updated each frame will multiply the number of rendering passes by six. 注意 Each light redraws mesh polygons it illuminates. That is why the higher the number of light sources, the higher the number of polygons the graphics card has to render, and the lower the performance. For example, using two omni lights will as much as double the rendered geometry they shine on.Each light redraws mesh polygons it illuminates. That is why the higher the number of light sources, the higher the number of polygons the graphics card has to render, and the lower the performance. For example, using two omni lights will as much as double the rendered geometry they shine on. Each light redraws mesh polygons it illuminates. That is why the higher the number of light sources, the higher the number of polygons the graphics card has to render, and the lower the performance. For example, using two omni lights will as much as double the rendered geometry they shine on.每帧渲染的光通过次数。这意味着计数器将显示当前看到的照明视口中的所有光源的数量。该值还包括用于在反射表面上渲染光的其他遍次（如果使用了动态反射）。普通的2D反射将渲染次数乘以2，而基于立方体贴图的反射（每帧更新了六个面）会将渲染次数乘以6。注意 Each light redraws mesh polygons it illuminates. That is why the higher the number of light sources, the higher the number of polygons the graphics card has to render, and the lower the performance. For example, using two omni lights will as much as double the rendered geometry they shine on.每个灯光都会重绘其照亮的网格多边形。这就是为什么光源数量越多，图形卡必须渲染的多边形数量越多，性能越低的原因。例如，使用两个全向光源将使它们照亮的渲染几何体增加一倍。
Shadows	Number of shadow passes rendered per frame. Each light requires a shadow pass to calculate the shadows. Again, if there are reflecting surfaces with shadows drawn reflected, this will increase the number of shadow passes.每帧渲染的阴影遍数。每盏灯都需要经过阴影才能计算出阴影。同样，如果有反射的表面带有绘制的阴影，则会增加阴影的通过次数。
Decals	Number of decals rendered per frame (in all rendering passes).每帧渲染的贴花数量（在所有渲染遍次中）。
Surfaces	Number of surfaces rendered per frame (in all rendering passes). Each light source doubles the number of surfaces if they are lit.每帧渲染的曲面数（在所有渲染遍次中）。每个光源在被照亮时都会使表面数量加倍。
Triangles All	Total number of triangles rendered per frameincluding all polygons that are currently visible in the viewport as well as the ones rendered in the process of shadows rendering.每帧渲染的三角形总数，包括当前在视口中可见的所有多边形以及在阴影渲染过程中渲染的多边形。
Triangles Shadows	Number of triangles rendered per frame in the process of shadows rendering. Each light source has to redraw the geometry it illuminates, increasing the overall count of rendered triangles. In order to avoid GPU bottleneck, keep the number of dynamic light sources and their radius as low, as possible.在阴影渲染过程中每帧渲染的三角形数量。每个光源都必须重新绘制其照明的几何形状，从而增加了渲染三角形的总数。为了避免GPU瓶颈，请保持动态光源的数量及其半径尽可能小。
Triangles Viewport	Number of triangles rendered per frame. This includes all polygons that are currently visible in the viewport (geometry).每帧渲染的三角形数量。这包括当前在视口（几何形状）中可见的所有多边形。
Primitives	Number of geometric primitives rendered per frame. This includes points, lines, triangles, and polygons. The visualizer and the profiler itself also add to this counter. The value differs dramatically if tessellation is used. In this case, Triangles reports the number of triangles in the coarse mesh, while Primitives shows statistics on the number of tessellated primitives.每帧渲染的几何图元数。这包括点，线，三角形和多边形。可视化器和分析器本身也添加到此计数器中。如果使用镶嵌细分，则该值会显着不同。在这种情况下， Triangles 报告粗糙网格中的三角形数量，而 Primitives 显示有关镶嵌细分图元数量的统计信息。
Dips	The number of draw calls. The higher the number of identical mesh surfaces with the same material, the more effective the instancing is (enabled by default). This means, the number of draw calls is minimized offloading both the CPU and the GPU. You can compare the number of surfaces ( Surfaces) and the number of DIPs used to render them. For example, if there are 30000 surfaces and 1000 DIPs, it means that 30 instanced surfaces of meshes are rendered per only one draw call (Surfaces/Dips). Thus the instancing provides performance boost. 抽奖电话数。具有相同材料的相同网格曲面的数量越多，实例化效果越好（默认情况下启用）。这意味着，绘图调用的数量得以最小化，从而减轻了CPU和GPU的负担。您可以比较表面的数量（Surfaces）和用于渲染它们的DIP的数量。例如，如果有30000个曲面和1000个DIP，则意味着仅一个绘制调用（Surfaces/Dips）将渲染30个实例化的网格面。因此，实例化可提高性能。
Shaders	Number of shaders set per frame. (Shaders are set in each of the rendering passes; hence if only one material used, its shader still needs to be set several times. When nothing is visible and the screen is black, even in this case the composite shader is still used.) 每帧设置的着色器数量。（在每个渲染过程中都设置了着色器；因此，如果仅使用一种材质，则仍需要对其着色器进行多次设置。当看不到任何东西且屏幕为黑色时，即使在这种情况下，组合着色器仍在使用。）
Materials	Number of materials set per frame. (Materials are set in each of the rendering passes.)每帧设置的材料数量。（在每个渲染过程中都设置了材料。）

注意

小于1 Mb的值显示为 0 。
