针对桌面 API 图形应用程序的帧分析

Graphics Frame Analyzer 使用帧捕获文件以逐帧可视化观察游戏内发生的确切情况。
典型的框架分析流程如下:
1.
要捕获一个特定的帧,可以:
  • 在游戏运行的同时,在 System Analyzer 或 System Analyzer HUD 中使用
    Ctrl+Shift+C
  • 在 System Analyzer 界面中,使用
    Capture Frame
    按钮。
  • 使用
    Graphics Monitor 界面中的一个选项,在某个“触发器”发生时(如帧速率降至低于 10 FPS 时)捕获一个帧。
可以捕获多个帧而无需停止并重新启动游戏。
2.
载入帧捕获文件
启动 Graphics Frame Analyzer 选择要分析的帧捕获。可在本地分析一个帧,或者连接到 Graphics Monitor 在运行的远程目标系统,以网络模式来分析帧。
3.
分析捕获的帧
