Performance tuning and debugging for DirectX 12 games on Windows
February 1, 2019Feb 1, 201902/1/19Today we released PIX-1901.28, which can be downloaded here. In this release we’ve made improvements to Timing Data in GPU Captures, added support for new GPUs from NVIDIA and AMD, and fixed miscellaneous other issues described below.
Timing Data Improvements for GPU Captures
We have significantly reworked how PIX collects Timing Data in GPU Captures.
December 18, 2018Dec 18, 201812/18/18Today we released PIX-1812.14, which adds support for selecting the playback adapter, displaying unbound resources and improvements to the occupancy lane. This release also includes various miscellaneous fixes detailed below.
Playback Adapter Selection
PIX now allows you to select the GPU on which to play back a recording.
October 29, 2018Oct 29, 201810/29/18Today we released PIX-1810.24, which adds support for the final DirectX Raytracing (DXR) API that’s part of the Windows 10 October 2018 Update (a.k.a. “RS5”). This release also fixes miscellaneous other bugs, including an incompatibility between PIX and the latest AMD 18.40+ drivers.
October 4, 2018Oct 4, 201810/4/18Release Notes
Today we released PIX-1810.02. This version includes:
Support for capturing Direct3D 11 apps on RS5
Support for capturing WinML workloads on RS5
Default file extension is now .wpix
Various bug fixes
Direct3D 11 on 12 Support
On RS5 PIX can now be instructed to use a Direct3D11-to-Direct3D12 translation layer to make GPU captures of Direct3D11 applications.
July 24, 2018Jul 24, 201807/24/18Today we released PIX 1807.19 which includes a new Shader Table Viewer.
The Shader Table Viewer has been added to the Pipeline View, which provides deep insight into a raytracing shader table’s contents.
The viewer visualizes how the shader table’s bytes will be interpreted by GPU.
June 13, 2018Jun 13, 201806/13/18Today we released PIX 1806.11 which includes numerous new and updated features:
Timing captures now track and visualize fence signals and waits to help you understand synchronization issues.
We have updated the WinPixEventRuntime to allow you to name fences to make it easier to locate interesting fences in a capture.
March 27, 2018Mar 27, 201803/27/18Today we released PIX 1803.25 which includes numerous new and updated features:
GPU Occupancy provides detailed insight into how shader workloads execute on the GPU. As announced at GDC we have collaborated with NVIDIA to bring console-level performance details about how shaders execute on the hardware to PIX on Windows.
March 19, 2018Mar 19, 201803/19/18Today we released PIX-1803.16-raytracing which adds experimental support for DirectX Raytracing (DXR).
As just announced at GDC this morning, Microsoft is adding support for hardware accelerated raytracing to DirectX 12 and with this release PIX on Windows supports DXR rendering so you can start experimenting with this exciting new feature right away.
November 30, 2017Nov 30, 201711/30/17Today we released PIX_1711.28. New in this release:
Timing captures now track GPU memory usage, and PIX can show how heaps and resources are created and managed with respect to the underlying GPU memory. This can be used to understand and optimize heap residency and troubleshoot performance issues caused by paging between local and non-local GPU memory.
September 19, 2017Sep 19, 201709/19/17Today we released PIX 1709.18.004 beta and an updated WinPixEventRuntime (version 1.0.170918004).
New in this release:
Dr. PIX “Bandwidth” page is now enabled on AMD and Intel
Access tracking for bindless resources
PIX now instruments shaders so it knows exactly what data was read or written via dynamic indexing
This makes the Pipeline view far more useful for titles that use bindless resource access model
By default,
