Today we released PIX 1704.27 beta. New in this release:
PIX warnings can now automatically detect some common but inefficient D3D12 usage patterns First couple of Dr. PIX queries are now available on Windows CPU hotpath analysis in timing captures Create sections of your package layout file from File IO captures Merge multiple traces into a single analysis in File IO captures Added support for new D3D APIs introduced with Windows 10 Creators Update (ID3D12Device2,
Today we released a bugfix update: PIX 1704.14-servicing. This resolves an incompatibility between PIX and the latest NVIDIA graphics drivers. This version is otherwise identical to the previous 1703.20.002 release (but stay tuned – we are hard at work on some new features that will be showing up soon).
From GDC 2017, Shawn Hargreaves and Max McMullen talk about D3D12 Performance Tuning and Debugging with PIX and GPU Validation. Seth Juarez talks to Brian Rasmussen from the PIX team and Cameron Egbert from the Minecraft team about debugging and performance optimization for DirectX 12 games with PIX on Windows.
Today we released PIX 1703.20.002 beta. New in this release:
NVIDIA GPU counters File IO traces Shader edit & continue Pixel Cost visualizer Improved Warnings UI. Where possible, warning hyperlinks now point to the GPU rather than CPU event list. Added an option to disable Capture GPU timings when taking timing captures.
If you are using PIX on a laptop which contains both integrated and discrete GPUs, you may be disappointed to notice that we currently¹ default to running the PIX analysis engine on the less powerful integrated part. For those who prefer to use the discrete GPU,
Today we released PIX 1702.23.002 beta. New in this release:
Rendertarget visualizers Improved Warnings user interface Memory captures now show allocated types On some hardware, the Pipeline view can now inspect individual sample values from MSAA rendertargets and depth buffers Shader debugging bugfixes Improved performance on captures that use tiled resources
Today we released PIX 1701.26 beta and an updated WinPixEventRuntime (version 1.0.170126001). The event runtime upgrade is optional, as the latest PIX is compatible with older event runtimes. Most of these changes are in response to early feedback from customers. Your input is valuable to us,
Welcome to our new PIX team blog! PIX is a performance tuning and debugging tool for game developers. It has a long and storied history spanning three generations of Xbox console. Today we are pleased to announce that a beta release of PIX is now available for analyzing DirectX 12 games on Windows as well.
Today 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.
If 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,
Today 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.
GPU 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.
A 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,
The 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.
The 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.
