About this tag
ETW profiling on WindowsForum.com covers the use of Event Tracing for Windows to capture low-level performance telemetry, with a focus on DirectX 12 graphics workloads. The tagged discussion highlights Microsoft's open-source DxTimingCaptureLibrary, a C++ library extracted from the PIX toolchain that lets game engines, in-house profilers, and other D3D12 tools consume DirectX event data directly instead of relying on PIX alone. Released under the MIT license and announced on the DirectX Developer Blog, it supports Windows 10 and Windows 11. Expect coverage of ETW-based capture, DirectX timing data, and developer profiling workflows.
