Today 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.
Today 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,
Today we released PIX 1707.25 beta.
New in this release:
GPU counter improvements
GPU counter values are now accurately rolled up from individual draws to their parent regions
Added support for some AMD R5xx GPUs that did not previously work with PIX
Improved accuracy of the crop__sol_pct and zrop__sol_pct counters on NVIDIA GPUs
Dr.
Today we released PIX 1706.25.002 beta and an updated WinPixEventRuntime (version 1.0.170625002).
New in this release:
System Monitor displays realtime counter data while a game is running
Present statistics (fps, frame duration, sync interval)
GPU memory usage (commitment, budget, demotions)
Custom title counters reported by the WinPixEventRuntime PIXReportCounter API
Continuous timing captures
Record timing data into a circular buffer (rather than just capturing a fixed duration),
PIX 1705.17 beta is now available for download.
This release introduces a partnership with Intel. We are pleased to announce that PIX now supports a set of ~200 hardware performance counters when running on a compatible Intel GPU. The new data includes processing counts,
Today we released PIX 1705.16 beta. New in this release:
AMD GPU counters
Preliminary support for DXIL (shader model 6)
More D3D12 usage warnings
Fixed problem capturing titles that use large numbers of resource heaps
HLSL syntax highlighting
AMD GPU Counters
We are delighted to announce a partnership with AMD to enable a rich set of hardware performance counters inside PIX.
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.
