Performance tuning and debugging for DirectX 12 games on Windows
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,
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”
March 27, 2019Mar 27, 201903/27/19Today we released PIX-1903.26, available for download here. This release includes support for Variable Rate Shading in GPU Captures, and it adds support for Occupancy on NVIDIA Turing GPUs such as an RTX 2080.
Variable Rate Shading
Variable Rate Shading (VRS) is a powerful new DirectX 12 feature that allows applications to significantly reduce their pixel shading work in exchange for minimal loss of visual fidelity.
March 13, 2019Mar 13, 201903/13/19Today we released PIX-1903.12, available for download here. This release includes an exciting new feature in GPU Captures: High Frequency Counters.
With High Frequency Counters, developers can plot graphs of GPU hardware counter values over time and correlate ranges of the graphs back to specific events within their GPU Capture.
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.
