Performance tuning and debugging for DirectX 12 games on Windows
August 22, 2019Aug 22, 201908/22/19Today we released PIX 1908.16 which can be downloaded here. This is a servicing release that fixes a couple of issues that causes PIX to crash when inspecting or debugging shaders, otherwise it is identical to PIX 1908.02.
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.
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,
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.
