What it does

This skill teaches an AI agent to operate NVIDIA Nsight Graphics, a professional GPU profiling tool, through a command-line wrapper. Once installed, the agent can check which Nsight install is present, launch or attach to a graphics application, capture a frame or GPU Trace, and summarize the results into performance hints such as bottlenecks and frame-budget classification. It can also analyse existing .ngfx-capture files using NVIDIA's ngfx-replay tool.

Great for

  • Graphics and game engine developers profiling a Direct3D, Vulkan or OpenGL application on Windows
  • Performance engineers who want a quick first-pass triage of a GPU trace
  • Teams that want an AI agent to run repeatable Nsight capture workflows and report the results

Skip it if

  • Users without an installed NVIDIA Nsight Graphics, since the skill only wraps that official tool and cannot profile on its own
  • People needing RenderDoc-style shader, texture or pipeline inspection, which the skill explicitly does not provide
  • Non-Windows users in most cases, as the skill is described as Windows-first

Try asking

  • “Check which Nsight Graphics versions are installed and recommend one for my game build”
  • “Capture a GPU Trace of my app at C:\Games\App.exe, export it and summarize the bottlenecks”
  • “Analyse my existing frame.ngfx-capture file and list the replay warnings and performance highlights”
  • “Attach Nsight Graphics to the running process with PID 12345 and capture a frame”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Run doctor info first so the agent discovers the correct compatibility mode and Nsight path before capturing.
  • Prefer gpu-trace capture with --auto-export and --summarize for a one-step performance overview; use replay analyze only for .ngfx-capture files.
  • Expect .ngfx-gputrace files may fail replay analysis with an invalid file header on Nsight 2026.1.0; use gpu-trace summarize instead.
