Performance tuning and debugging for DirectX 12 games on Windows
August 5, 2019Aug 5, 201908/5/19If you’re running the 1903 build of Windows 10 (the Spring 2019) update, you must have KB4505903 installed to take Function Summary, Callgraph, and Tracked Functions captures. Without this update, your title will hang when taking one of these captures.
To check whether you have this update,
August 5, 2019Aug 5, 201908/5/19Today we released PIX 1908.02, which can be downloaded here. This release fixes miscellaneous bugs that were reported to us by customers. It also adds new CPU features to New Timing Captures, and adds some final touches to the new DirectX Raytracing (DXR) Pipeline View in GPU Captures.
July 11, 2019Jul 11, 201907/11/19GPU timing data was added to the New Timing Captures preview feature in the PIX 1906.14 release. This allows developers to view GPU work submission and execution, including async compute.
Getting Started
The application should be launched with the following GPU timings checkbox checked in the options to enable timing data collection.
June 28, 2019Jun 28, 201906/28/19Today we released PIX 1906.26, available for download here. This release makes PIX compatible with the latest Insider Preview builds of Windows.
Highlights
PIX now works on latest Inside Preview builds of Windows.
PIX no longer pops up an error message when trying to use a plugin with an unsupported GPU configuration (eg SLI).
June 17, 2019Jun 17, 201906/17/19Today we released PIX 1906.14, available for download here. This release adds GPU timings to the New Timing Capture preview and further improvements to DXIL shader debugging.
Highlights
New Timing Capture Improvements
Support for GPU timing data (see below)
Many other usability improvements,
June 3, 2019Jun 3, 201906/3/19A context switch occurs when a CPU core switches from executing code on one thread, to executing code on a different thread, or going to idle. When the OS switches the thread that is running on a CPU, it must save and restore state both for the thread that is being switched out,
May 21, 2019May 21, 201905/21/19The most common way to populate the Range Details view in the new implementation of PIX Timing Captures is to drag select a range of time in the Timeline using the mouse. When you complete your selection, Range Details is populated with the data from all Thread and Core lanes for the range of time you selected.
May 7, 2019May 7, 201905/7/19The Metrics view in New Timing Captures allows you to graph the duration of PIX CPU events and any counter values that are reported using the PIXReportCounter API. Graphing event durations is fairly discoverable in the UI, but I think it’s less well-known that counter values can be graphed as well.
May 7, 2019May 7, 201905/7/19A few weeks ago we released a version of PIX that includes a Preview release of a new implementation of Timing Captures. This release represents a significant reboot of our CPU performance tools in PIX.
We’ve gotten a lot of feedback over the last few years about how our CPU tools in PIX compare with other AAA game-focused profiling tools.
April 24, 2019Apr 24, 201904/24/19Today we released PIX 1904.23, available for download here. This release contains a preview of the new Timing Capture implementation and improvements to DXIL shader debugging and pixtool as well as various other improvements and bug fixes.
Highlights
Preview of a new implementation of Timing Captures (see below)
HLSL variables are now available during DXIL shader debugging
New pixtool features:
Use “take-capture –winml”
