Developer Tools Nsight Systems Announcements
1

The latest update to NVIDIA Nsight Systems - a triage and performance analysis tool designed to track GPU workloads to their CPU origins within a system-wide view. These features help you analyze your applications’ GPU utilization, graphic and compute API activity, and OS runtime operations. This helps optimize your application to perform and scale efficiently across any quantity or size of CPUs and GPUs—from workstations to supercomputers.—is now available for download. Nsight Systems 2026.1.1 introduces several improvements aimed to enhance the profiling experience.

2026.1.1 Highlights

  • Pytorch profiling improvements - display shape and training parameters for forward and backward extension modules

  • Python sampling - added support for Python 3.14

  • GPUDirect Storage Metrics - new option to capture metrics of GPUDirect Storage DMA operations

  • WDDM Trace new option: WDDM Memory Trace

    • This option captures a focused set of WDDM memory events to track VRAM management. This generates reduced overhead and smaller report files allowing longer trace sessions focused on Windows Graphics VRAM management.

    • Note: The default settings for WDDM trace have changed and this new option is the new default for WDDM trace.

  • ETW trace - added support for ETW providers that implement TraceLogging

  • Graphics VRAM Usage Recipe

    • Support D3D12 placed and reserves resources

    • Support Vulkan resources

  • Vulkan trace - added support for VK_EXT_mesh_shader extension

  • The –nvprof CLI option has been removed from the tool

  • Export changes

    • Text and JSON export options are removed from both the CLI and the GUI. Using these options (e.g. nsys export --type=text or nsys profile --export=json ...) will result in an error. In this release, this can be circumvented by setting the NSYS_ENABLE_DEPRECATED_TEXT_EXPORT=1 and NSYS_ENABLE_DEPRECATED_JSON_EXPORT=1 environment variables respectively, but make sure to adjust your affected processes/scripts, as in the next release these options will be completely removed.

    • Instead of the JSON export option, the jsonlines option is now available. Similarly, it produces a text file with one JSON object per line, but in a slightly different format compared to the old json export.

  • NVIDIA Nsight Streamer improvements now available on NGC for viewing reports on remote headless servers

  • NVIDIA Nsight Operator for Kubernetes improvements - Releasing soon on NGC

Nsight Systems is part of the powerful debugging and profiling NVIDIA Nsight Tools Suite. A developer can start with Nsight Systems for an overall system view and avoid picking less efficient optimizations based on assumptions and false-positive indicators.
