Nsight Graphics 2025.2 is available now. In this release spotlight, we explore the newest features for high-performance graphics development.

This year, NVIDIA introduced the RTX Blackwell GPU Architecture, along with RTX Kit, a suite of neural rendering technologies to ray trace games with AI, render scenes with immense geometry, and create game characters with lifelike visuals. With so many powerful APIs and libraries available to graphics developers, it is more important than ever that developer tools stay up to date with these features, to make graphics profiling and debugging as easy as possible.

To meet this need, we are thrilled to introduce Graphics Capture, the new foundation for capture and replay of D3D12 and Vulkan applications in Nsight Graphics. Similar to the Frame Debugger activity, Graphics Capture provides user interfaces to inspect API calls, resources, shaders, and ray tracing acceleration structures. The workflow, however, has been modernized by separating the process of capture and visual debugging into distinct activities.

While an application is running, triggering a capture saves all API activity for one or more consecutive frames to a persistent file on disk. The target application continues to run, and additional captures can be taken. Capture files can be opened right away, saved for later, or shared with other people.

When you’re ready to inspect a capture, open the document and choose Start Graphics Debugger. This enters into a low-overhead mode displaying metadata from the capture, but without having to fully initialize and replay the entire captured application. There’s a lot of rich information that can be gathered in this mode, and you can even use the Ray Tracing Inspector.
To inspect all resources and state, start a Live Replay. This mode will use the GPU to re-render the frame. You can scrub between events, navigate resource revisions, and see how your frame is composed in detail with Live Replay mode.

Graphics Capture is where you can find support for capturing and inspecting features introduced in RTX Kit, including RTX Mega Geometry, Linear Swept Spheres, and Cooperative Vectors, used for Neural Shading.

Graphics Capture is currently in Beta status, but has already been used extensively within Nvidia and is rapidly maturing. Please try it out and share your feedback with the Nsight Graphics team by using the feedback button in the upper right corner of the tool.
