Aplicación Interesante

NVPerfKit gives you access to low-level performance counters inside the driver, and hardware counters inside the GPU itself.  The performance counters are available to OpenGL and DirectX applications via the Windows Management Instrumentation (WMI) Performance Data Helper (PDH) interface and the PIX for Windows NVIDIA Plug-in.

The counters can be used to determine exactly how your application is using the GPU, identify performance issues, and confirm that performance problems have been resolved. Now, for the first time ever, this confidential information is available to third party developers.

Por cierto, alguien me podria explicar que es el PIX?

 Pues te pego lo que pone la documentación de la utilidad PIX que viene con el SDK de DX (no sé si será lo mismo que la herramienta de nVidia):

PIX is a tool for analyzing applications that use Direct3D. It has a wide variety of uses, both for programmers and for quality assurance engineers, depending on how it is configured. PIX can be used to perform tasks such as:

• Gathering and analyzing statistics to help understand why some frames render more slowly than others.
  
• Gathering and analyzing statistics to identify inefficient usage of APIs and system resources.
  
• Monitoring daily builds of an application for unexpected changes in performance or appearance.
  
• Grabbing and comparing screen shots of the application running in different circumstances, such as a hardware abstraction layer (HAL) device versus a reference device (see Device Types).
  
• Capturing and replaying a full Direct3D call sequence to use for further analysis or for bug reporting.

Eso sí, no la he utilizado nunca...

 Merci!

Alguien la ha utilizado? O alguna otra herramienta de análisis de rendimiento?
