PIX 1812.14 – Playback Adapter Selection
Today 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. After opening a wpix file, use this drop-down control in the top-right corner before starting analysis. Note that workloads that explicitly use multiple adapters will be played back exclusively on the selected adapter, rather than on the default adapter as in previous versions of PIX. Chang...
PIX 1810.24 – Support for final DirectX Raytracing API
Today 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. Features available in PIX to help developers debug their DXR applications include: Please note that PIX can no longer be used to debug applications that use the experimental DXR API that was announced during GDC 2018. Developers still using the experimental DXR API should strongly consider moving their applications to ...
PIX-1810.02 – Direct3D11 and WinML
Release Notes Today we released PIX-1810.02. This version includes: 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. At playback, the PIX UI will show the resulting Direct3D12 calls but will offer no mapping back to the Direct3D11 calls made by the application. Enable this mode via the "API" drop-down in the "Select Target Process" box on the PC Connection tab: Source-level shader debugging is not available in this mode. Also of note on RS5, if the above option is not selected, PIX wi...
