Introduction


PIX is a performance tuning and debugging tool for Windows and Xbox game developers using DirectX 12.  It provides seven main modes of operation:

  • GPU captures for debugging and analyzing the performance of Direct3D 12 graphics rendering.
  • Timing captures for understanding the performance and threading of all CPU and GPU work carried out by your game, and for tracking GPU memory usage.
  • Function Summary captures accumulate information about how long each function runs for and how often each is called.
  • Callgraph captures trace the execution of a single function.
  • Memory Allocation captures provide insight into the memory allocations made by your game.
  • File IO captures help you identify inefficiencies in your title’s disk IO patterns and package layout.
  • System Monitor displays realtime counter data while a game is running.
