Release Notes  

# Nsight Graphics 2026.2

* * *

## NVIDIA® Nsight™ Graphics 2026.2 is released with the following changes

## New Features:

### Graphics Capture / Graphics Debugger

**\>** Added support for capture and replay of Vulkan descriptor heaps as provided by the [VK\_EXT\_descriptor\_heap](https://docs.vulkan.org/guide/latest/descriptor_heap.html) extension.

- 

Capture and replay currently requires use of the beta Vulkan driver, [available here](https://developer.nvidia.com/vulkan-driver).

- 

Both "untyped" (direct heap access) and "typed" (mapped) resources are shown in the API inspector. Mappings can be inspected in the Object Browser on the relevant pipeline or shaderEXT objects, via “pNext \> pMappings”.

- 

GPU-driven modifications to the heap are not currently tracked.

- 

For testing, download and run the descriptor heap sample at this [link](https://github.com/nvpro-samples/vk_mini_samples/tree/main/samples/descriptor_heap), or launch directly from the “Help \> Samples” menu.

**\>** Graphics Capture now supports Vulkan SC on Windows/Linux.

### GPU Trace

- 

When "Per-Line Active Threads per Warp" has been collected (an option when collecting a GPU Trace on a Graphics Capture), a new column "Inactive Thread Latency %" is available in the Shader Profiler source views. It helps hone in on what code could benefit the most from increasing active threads per warp. For more information, see [this section of the Shader Profiler documentation](https://docs.nvidia.com/nsight-graphics/UserGuide/shader-profiler.html#source-correlation).

## Improvements:

### Overall

- 

This release dramatically improved the stability and reliability of Nsight Graphics with hundreds of bug fixes, as well as numerous usability improvements.

- 

The [hosted Nsight Graphics documentation](https://docs.nvidia.com/nsight-graphics/index.html) now solicits your feedback. Click on “Is this page helpful?” on any page to send us suggestions and requests for improvements to the docs.

### Graphics Debugging

- 

You can now search all files at once within a shader’s source in the Shader Editor view. Click the vertical “Search” tab on the left side of the view to toggle the expanded search panel.

* * *

## Deprecations:

- 

Pascal Architecture based GPUs are no longer supported.

* * *

## Known Issues:

### GPU Trace Profiler, Frame Debugger Shader Profile, Frame Debugger Batch Histogram

- 

Some GPU SKUs not typically encountered on consumer desktop systems may report "Unsupported GPU" errors. See [this page](https://developer.nvidia.com/err_nvgpu) for more information.
