包含基本 FrameTimings 并且随附相关数据的结构。
| cpuFrameTime | This is the total CPU frame time calculated as the time between ends of two frames, which includes all waiting time and overheads, in ms. |
| cpuMainThreadFrameTime | Total time between start of the frame and when the main thread finished the job, in ms. |
| cpuMainThreadPresentWaitTime | The CPU time the last frame spent in waiting for Present on the main thread, in ms. |
| cpuRenderThreadFrameTime | The frame time between start of the work on the render thread and when Present was called, in ms. |
| cpuTimeFrameComplete | 这是 CPU 时钟时间，此时 GPU 完成了帧渲染并且中断了 CPU。 |
| cpuTimePresentCalled | 这是 CPU 时钟时间，此时为当前帧调用了 Present。 |
| firstSubmitTimestamp | This is the CPU clock time of the time when the first job was submitted to GPU. |
| frameStartTimestamp | This is the CPU clock time of the time when the frame was started. |
| gpuFrameTime | 给定帧的 GPU 时间（单位为 ms）。 |
| heightScale | 这是用于给定帧和关联帧计时的动态分辨率系统（如果使用）的高度缩放因子。 |
| syncInterval | 这是用于给定帧和关联帧计时的 vsync 模式。 |
| widthScale | 这是用于给定帧和关联帧计时的动态分辨率系统（如果使用）的宽度缩放因子。 |
