NVPerfHUD ES performance tool for handheld GPUs shown at SIGGRAPH

At SIGGRAPH NVIDIA showed NVPerfHUD ES, a new performance tool for handheld GPUs. This is a comprehensive suite of performance tools to help debug and profile OpenGL ES applications by giving 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. It works well in conjuction with gDEBugger ES.
