PIX 1705.17 – Intel GPU counters
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, busy percentages, and bottleneck information from different parts of the rendering pipeline, and also covers memory bandwidth and cache usage. This can help PIX users optimize their titles to run efficiently on Intel hardware. Intel GPU counters are supported on 6th Generation Intel Core Processors or newer (e.g. Skylake and Kabylake). They...
PIX 1705.16 – AMD GPU counters, preliminary DXIL support, and more warnings
Today we released PIX 1705.16 beta. New in this release: AMD GPU Counters We are delighted to announce a partnership with AMD to enable a rich set of hardware performance counters inside PIX. When running on an AMD GPU with the latest driver (17.5.1) you will see ~90 newly available counters that can be added to the PIX event list. Information such as hardware utilization and bottlenecks can help PIX users better optimize their titles to make efficient use of AMD hardware. Many thanks to our partners at AMD for making this possible! Note that not all counter values are currently rol...

Today we released PIX 1704.27 beta. New in this release: Warnings New GPU capture warnings are available in the Warnings pane. To analyze a capture for them, click on Collect Experimental Warnings. Each new warning will be marked experimental until we build up confidence that it is working reliably and not reporting too much noise. We would greatly appreciate feedback about whether useful warnings were reported for your title, any false positives, suggestions for other things you would like PIX to warn about, etc. Warnings added in this release are: ...
PIX 1704.14-servicing – graphics driver compatibility fix
