nVidia PerfKit

[Wizardskills]

NVIDIA PerfKit is a comprehensive suite of performance tools to help debug and profile OpenGL and Direct3D applications. It gives you access to low-level performance counters inside the driver and hardware counters inside the GPU itself. 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.

* GeForce 8 Series support on Windows Vista and XP
* DirectX 10 support on Windows Vista
* DirectX 9 support on Windows XP and Windows Vista
* New in 5.1! Support for Managed and XNA applications

o Hardware mouse cursor improves responsiveness when frame rate is low
o Clicking on graphs in Frame Profiler jumps to corresponding draw call
o Clear legends for all graphs
o New Help screen with software version, GPU, driver information, and keyboard shortcuts
o Options screen with numerous configuration options:
+ Clear color buffer when viewing Z-only passes

* Compatibility, stability, and reliability improvements
o Extensive testing on a wide range of applications
o New in 5.1! Allow API specification (DX9/DX10/both) for apps that create devices from both APIs
o Minor bug fixes

I just found out about this program that does detailed analysis of a DirectX or OpenGL programs graphic performance on your card. According to the guide video it can monitor core usage, shader usage etc and bottlenecks within the game. Might it be a good tool for analyzing the performance differences of graphics cards?

Just thought some people might find it interesting

Dunno if it shows it - but it would be interesting to see how much useage there is on the PCI-e bus with modern GPUs...

everything I've tried with it didn't work

Hope it better then n-tune

Sounds like a game developers tool to me.
