NVIDIA has rolled out the 2019.4 version of Nsight Graphics. Nsight Graphics is a tool that allows developers the access to debug, profile, and export frames built with Direct3D, Vulkan, OpenGL, OpenVR, and the Oculus SDK. It is standalone to other NVIDIA products and is extremely versatile.
In response to user requests, profiling OpenGL applications using Turing based GPUs is now supported in the Range Profiler. You can find expensive perfmarker ranges within your frame and drill down using detailed hardware performance metrics to find optimizations within your frame. For more information about profiling applications with the Range Profiler, check out Louis Bavoil’s Peak Performance Percentage Method.
In this update, they've added support for OpenGL 4 as well as SPIR-V. Additionally, they've included basic immediate mode functionality, giving developers with legacy code access to debugging and profiling.
