NVPerfKit 1.0 RC1 Available
 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.

Convolution Filters Sample Released
 This example shows various methods of implementing convolution filters in OpenGL using Cg. It supports both 1D separable filters (such as Gaussian blur) and 2D filters (such as disc blurs). The code shows how to take advantage of bilinear texture filtering so that only half the usual number of texture samples are required for separable filters. It also demonstrates how to implement steerable filters, where the width of the filter can vary from pixel to pixel.

Nature Scene Code Sample
 This OpenGL code sample combines several techniques to produce a realistic looking natural scene. Notice the wind blowing through the grass and rippling across the lake as the clouds pass by overhead. The gently swaying grass is rendered using Transparency Antialiasing to ensure it looks great even in the distance, and the horizon is tinted using an exponential fall off effect. Several textures and a pixel shader are used to create the diverse terrain. A helpful whitepaper is included that explains all of these techniques in detail.
