NVIDIA Nsight Graphics

Track GPU Performance

Analyze GPU throughput and utilization with minimal overhead for non-biased activity data. On the captured timeline, drill down into critical performance markers and inspect hardware unit throughputs, cache hit rates, memory throughput, and more. 

Analyze GPU Traces

Nsight Graphics supports automated performance analysis on captured GPU traces. Deep profiling of streaming multiprocessor (SM) performance is accomplished by automatically tracing the execution of shaders across a series of frames.

Debug Ray-Tracing and Shaders

Debug ray-tracing API calls and examine their state. The Ray Tracing Inspector exposes acceleration structures, helping you optimize how rays intersect with the geometry in your scene. You can also examine ray tracing efficiency to ensure ray-traversal speeds are high.

Debug shader code with the Vulkan Shader Debugger, which exposes shader source in your render pipeline in real-time so you can quickly make fixes directly to the  code.

Profile Ray-Tracing Shaders

The Nsight Graphics Shader Profiler exposes shader data, including stalls and the reasons they occurred. The Real-Time Shader Profiler allows you to view the most expensive shaders at each moment in real-time. And the shader timing heatmap visualizes hotspots overlaid on the scene where shader times lagged per pixel.

Profiling ray-tracing shaders can be an arduous task that requires extensive knowledge of the GPU. These features turn ray-tracing profiling into a streamlined and intuitive process.

Export C++ Capture

Create a self-contained C++ project that allows for frame analysis in a reduced CPU-load scenario. This lets you perform repeatable and isolated analysis without being bound to the original application and provides a protected environment for experimenting with optimization tweaks.
