Thank you to everyone who reported issues and suggestions to us. Please keep them coming! The best ways to contact us are via the DirectX Discord and via the Send Feedback buttons in PIX.

Today we released PIX 2602.25 and 2602.25-preview, which can be downloaded here. These releases include everything in the previous 2601.15 release, plus:
- 2602.25: includes support for all of the new D3D12 features released today in Agility SDK 619.0, including Shader Model 6.9, DXR 1.2 (OMMs, SER), revised view creation, and more.
- 2602.25-preview: includes everything in 2602.25, plus support for new D3D12 preview features in Agility SDK 719.0 such as fence barriers and extensions.
By default we recommend that all PIX users use non-preview versions of PIX (e.g. 2502.25). We only recommend that you use preview versions of PIX (e.g. 2602.25-preview) if you are trying out new preview D3D12 features.
Both versions of PIX include correctness fixes and quality-of-life improvements listed below. As usual, please get in touch with us if you have any feedback or hit any issues! The best ways to contact us are via the Send Feedback button in PIX or via the #pix channel on the DirectX Discord server.
Correctness fixes
- Fix ResolveQueryData() performance regression in 2601.15
- Fix command list batching when collecting timing data on Qualcomm devices
Quality-of-life improvements
- Fix PIX launching off-screen after monitor disconnect
- Automatically select all text when tabbing between textboxes
- Fix invisible textbox caret in dark mode

Today we released PIX version 2601.15, which can be downloaded here. This release includes everything in the previous 2509.25 release, plus:
- A new Intel plugin with many new features and improvements
- Many new Buffer Viewer and Buffer Formatter improvements
- Misc other bug fixes and improvements
As usual, please get in touch with us if you have any feedback or issues. The best ways to contact us are via the Send Feedback button in PIX or via the #pix channel on the DirectX Discord server.
New Intel Plugin
This version of PIX includes a revamped plugin from Intel, giving you a far better profiling experience for Intel GPUs in PIX than ever before. Many thanks to our partners at Intel for making this happen! Improvements include:
- New counter graphs, including a “bottleneck”-style Xe GPU Utilization lane
- Major counter accuracy improvements
- Major counter collection speed improvements

For a lot more information about the plugin and advice on how to use it, please see Steven Tovey’s presentation at the Graphics Programming Conference in November.

Buffer Viewer Improvements
We have made a lot of improvements to the Buffer Viewer and the Buffer Formatter in this release.
The buffer formatter is now automatically populated for constant buffers in raytracing shaders, based on reflection data and/or shader symbol data:

We have added a button to export the contents of the buffer view to CSV:

A new vector keyword (e.g. vector<float32_t, 4>) has been added. This also enables long vectors, no longer limited to 1-4 elements:

Arrays work in table view now, including multiple dimensions in tree and table view. e.g. uint8_t x[12][16]:

We’ve added a new tensor pseudo-keyword that supports any data type (primitive and structures), dimensions, element strides, and layout (e.g. tensor<float32_t, {128,64}>). Strides can specify element order (e.g. tensor<float32_t, {12,7}, column_major>) and explicit dimension alignment for padding (tensor<uint32_t, {12,7}, {8,1}>). Higher dimensions can be semantically labeled and flattened onto a 2D view. e.g. tensor<float32_t, {3,4,5,6}, default, nchw> or tensor<float32_t, {12,16}, row_major, xy>. Axis remapping is also supported via a 5th parameter to rearrange elements in the view, for example to show an NCHW layout as NHWC with the channels adjacent. e.g. tensor<float32_t, {1,3,4,5}, default, nchw, nhwc>:

We added a using keyword added for type definitions, which supersedes macros, honoring scope and enabling array definitions. e.g. using uint32_t8 = uint32_t[8]:

#define macro definitions are more generic, supporting arbitrary tokens which is useful for other scenarios (like say defining an array which wasn’t possible with macros). e.g. #define ARRAY_LENGTH 42:

We added more direct previews in the value column without needing to explicitly expand the rows to see them. New (above) vs old (below):

Expanding all/selected rows and columns is now possible via context menu and keypresses (NumPad * expand all children, double click toggles). Expanding a node that contains a nested series of single nodes will just expand that whole series, saving clicks:

Hierarchy context is preserved in table view for nested single node structures:

Additionally:
- The buffer formatter view is now populated before start analysis, and far more quickly than before.
- We added a field offset column added to tree view.
- Constant buffers and UAV’s now follow natural field alignments without needing all the explicit padding (though explicit padding an [[offset(28)]] still work).
- Matrix shapes 2×3 and 3×2 now show correct offsets and values.
- New data types added: int8_t, float8m3e4s1_t, float8m2e5s1_t.
- Mouse wheel scrolling is faster, rather than a single line per scroll.
- Bitfields honor big endian option.
- Binary values 0b show consistent digit counts.

Misc Other Improvements
GPU Captures
- Strip DENY_SHADER_RESOURCE from acceleration structures created via enhanced barriers to fix some capture/replay issues

Today we released PIX version 2509.25, which can be downloaded here. This release includes everything in the previous 2507.11 release, plus:
- A compatibility fix to make PIX work on Windows 11 24H2 or 25H2 with KB5065789 (KB released 24 Sept 2025)
- An updated AMD plugin with better data accuracy and new hardware support (including ROG Xbox Ally devices)
- Support for new features in today’s DirectX Agility SDK release
- Misc bug fixes + improvements
Patch Tuesday Compatibility Fix
TL;DR: If you are hitting errors where PIX says that it can’t enable experimental features, then please update to PIX 2509.25 and try again.
More details: Windows 11 update KB5065789, initially released as a preview on 9/24/2025, updates the system32 copy of D3D12Core.dll to be roughly the same as DirectX Agility SDK 616.1. That new Agility SDK introduced a breaking change to the D3D12EnableExperimentalFeatures() API: it is no longer valid to call that API in a non-preview Agility SDK. Unfortunately PIX builds prior to 2509.25 unconditionally try to turn on some experimental features, so they hit errors after KB5065789 is installed. This is fixed in PIX 2509.25 and later.
Updated AMD Plugin
This release includes a new AMD plugin, which exposes hardware-specific functionality such as counter data inside PIX. The new plugin includes:
1. Support for new devices, including the ROG Xbox Ally and ROG Xbox Ally X devices
2. Greatly improved accuracy of counter and occupancy data on the GPU Capture timeline, on all AMD devices
Many thanks to our partners at AMD for their work and support!
Support for new Agility SDK Features
Today the DirectX team released DirectX Agility SDK version 618. This primarily includes support for new Advanced Shader Delivery (ASD) tooling. This tooling is independent of PIX, so today’s PIX build doesn’t include new corresponding functionality. However, PIX is fully compatible with all new Advanced Shader Delivery APIs, and in the future we will add PIX features to make it easier to integrate ASD into your application – such as showing ASD cache misses in Timing Captures. Stayed tuned to this blog for more updates in the coming months!
Agility SDK 618 also promotes several features out of preview, and today’s PIX release includes full support for them. These features include:
- Application-Specific Driver State
- Recreate-At-GPUVA
- Tight Alignment
The first two features were added to D3D specifically to improve capture/replay accuracy in tools like PIX:
- Application-Specific Driver State: this captures an opaque blob from the driver that represents any app-specific settings or workarounds enabled by the driver. PIX then passes this blob back to the driver at replay-time, so that the driver can apply the same settings or workarounds. This improves capture/replay reliability on many drivers.
- Recreate-At-GPUVA: during playback, this feature lets PIX recreate buffers at exactly the same GPUVA as they used at capture time. This means that features that use GPU buffers that contain GPUVAs, such as ExecuteIndirect argument buffers or DXR Shader Tables, can be replayed more easily and accurately.
These features are turned off by default in PIX, but they can be enabled via the Settings page. They will be turned on by default in a future version of PIX.
