Santa Clara, Calif. - Nvidia Corporation has announced NVPerfKit 2.1, a suite of next-generation performance tools for the debugging and profiling of OpenGL and Direct3D software applications for Windows and Linux.
Developers working on 32- and 64-bit Linux or Windows platforms can now benefit from the same technology that powers the Nvidia NVPerfHUD performance analysis tool, a profiling and visual debugging heads-up display (HUD) program for Direct3D applications supporting Microsoft DirectX 9.0c and Windows XP on select Nvidia graphics processing units (GPUs).
By offering access to low-level performance counters inside the driver, as well as hardware counters inside the GPU, NVPerfKit 2.1 helps developers determine how applications use the GPU by identifying and confirming resolved performance issues for substantial time savings during application development.
NVPerfKit 2.1 offers:
-- Instrumented Driver Interfaces with the graphics API and GPU to provide performance counter data
-- NVPerfHUD, offers advanced real-time analysis of Direct3D applications
-- NVPerfSD, includes an API for accessing GPU signals in applications, sample code and helper classes for OpenGL and DirectX applications, and an NvidiaDeveloper Control Panel and instrumented driver
-- Nvidia plug-in for Microsoft PIX for Windows
-- GLExpert, which permits debugging of OpenGL usage errors and performance issues
-- Support for PerfMon, Intel VTune, gDEBugger, and other analysis tools
NVPerfKit 2.1 supports Windows XP and Linux on Nvidia GeForce 7 Series GPUs, Nvidia GeForce 6 Series GPUs, and Nvidia Quadro FX or more recent NvidiaGPUs; older GPUs are supported with reduced functionality.
