At SIGGRAPH, NVIDIA researchers showcased the latest advancements in AI models for rendering and simulation, bringing photorealistic graphics closer to reality. AI-powered real-time graphics demand highly optimized algorithms to fully utilize NVIDIA hardware. To support this, NVIDIA has introduced new features in Nsight Tools, enhancing graphics profiling and debugging.

Nsight Graphics 2024.2 debuts the Shader Debugger public beta, a real-time, hardware-accelerated debugging tool for Vulkan applications. It allows developers to inspect and fix shaders live, facilitating fast iteration and improved development time. The Shader Debugger offers a CPU-like debugging workflow with breakpoints, variable inspection, and step-through capabilities at every rendering stage. The Focus Picker overlays shader fragments on the render target, aiding in pinpointing debugging efforts visually. The Shader Debugger is now available in beta for Vulkan applications.

On the profiling side, GPU Trace includes several new features. The Flame Graph generated from the NVIDIA RTXGI sample visually represents shader performance, highlighting time-consuming shaders and their callstacks. The Shader Pipelines view identifies ray tracing traversal costs, and the timeline reveals render passes from the NVIDIA Neural Rendering Cache, aiding in the integration of complex path tracing SDKs. GPU Trace now supports the CUDA API, allowing inspection of CUDA launches, API calls, and kernel profiling.

DirectX Work Graph profiling enhancements include identifying the most expensive Node shader at each point in time. The Shader Pipelines tab selection reveals shaders running during a specific period when you select a timespan.

Nsight Systems, NVIDIA's system profiler, has improved performance tracing for video accelerators like NVENC and NVDEC, correlating events with API calls and highlighting related traces. It also enhances resource migration tracking on Windows, displaying VRAM commitments over time, and identifying Vulkan resources bound to migrated memory pages, helping manage critical resources to avoid performance loss.
