Intel PresentMon (console application)

  • File: ThirdParty/PresentMon/PresentMon-2.5.1-x64.exe
  • Version: 2.5.1 (pinned)
  • Source: https://github.com/GameTechDev/PresentMon/releases/tag/v2.5.1
  • SHA-256: 9BEC3083069F58F911E6A512F4806DB51A27BD096103087BC1D05EF54C80A191
  • License: MIT (Intel Corporation) — see ThirdParty/PresentMon/LICENSE.txt
  • Used for: FPS/frametime capture via Windows ETW present tracing (spawned as a child process with --output_stdout; no code is linked).

CI verifies the hash above before packaging a release.

NuGet packages (shipped in release builds)

  • CommunityToolkit.Mvvm (MIT) — MVVM source generators for the WPF app.
  • Vortice.Direct3D11, Vortice.D3DCompiler, SharpGen.Runtime (MIT, Amer Koleci & contributors) — Direct3D 11 bindings used by the stress test's compute workload.
  • System.Diagnostics.EventLog (MIT, .NET Foundation) — Windows event-log watcher for TDR detection.

Test-only: xunit, Microsoft.NET.Test.Sdk, coverlet.

Knowledge provenance (no code copied)

The NVAPI interface IDs and the general-purpose structure layouts used by Afterglow.Core are constants published by open-source projects (LibreHardwareMonitor, MPL-2.0; NvAPIWrapper, MIT) and were re-declared in this codebase from those references — see docs/research/driver-apis.md for the provenance table.

The per-point V/F clock-boost layouts specifically — the NvClockMasks, NvVfpCurve and NvClockTable structures and the Get/Set call sequence behind the per-point curve editor — were derived from the field-proven layouts in nvapioc by Demion (https://github.com/Demion/nvapioc), as the source comment at src/Afterglow.Core/Interop/Nvapi/NvapiNative.cs records; the delta scale was then calibrated live against a known global offset on RTX 5090. No code is copied from nvapioc — only the wire layouts and call order, which are functional interface facts — and Afterglow re-declares them independently. Its license could not be confirmed from the information available offline in this repository; it is credited here as the reference these layouts were derived from, and its license is unconfirmed. (The earlier, broken 80+23 layout Afterglow once used — the one behind the retracted "RTX 50 blocks the curve interfaces" claim — was the NvAPIWrapper/LHM-style layout, not nvapioc's.)

The IGCL and Level Zero Sysman structure layouts in Afterglow.Core/Interop/Igcl and Afterglow.Core/Interop/LevelZero were transcribed field-for-field from Intel's own published headers — igcl_api.h (Intel Graphics Control Library, MIT) and zes_api.h (oneAPI Level Zero, MIT) — and are pinned by unit tests against compiler record-layout dumps of those headers. No Intel code is copied or linked; both runtime libraries (ControlLib.dll, ze_loader.dll) ship with the Intel graphics driver and are loaded from System32 at run time. See docs/research/intel-driver-apis.md for the per-interface provenance table and the dump procedure.
