Microsoft Release PIX Performance/Debugging Tool


Microsoft have just released a beta version of PIX, a performance tuning and debugging tool aimed at game developers.  Previously only available on XBox consoles, PIX is now available for Windows machines for games running Direct X 12.pixscreenshot


About PIX:

PIX on Windows provides five 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.
  • 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.

For best results we recommend running PIX on:

  • Windows 10 build 14393 (Anniversary Update, aka RS1) with latest updates
  • 32 GB RAM
  • A Direct3D 12 GPU with the latest available graphics drivers.  PIX will not work correctly with older drivers!

See the requirements page for more information.


The beta is free and is available for download here.
