We've created two new PerfHUD screencasts, each about 2 minutes long, to introduce you to new features in PerfHUD 6:

  • Texture Visualizations and Overrides
  • Performance Dashboard and SLI

Texture Visualizations and Overrides

This video shows you how to visualize your textures in a full screen, as well as how to override textures with useful debug textures on a per-texture basis, including the mipmap visualization texture.

Performance Dashboard and SLI

This video teaches you how to use several Performance Dashboard features:

  • Speed Control - Pause or slow down your applications speed to isolate difficult to capture effects.
  • The SLI Graph - View hardware performance counters on every GPU in your system.
  • Custom layouts - Save and name your Performance Dashboard layouts so you can bring them up at any time.

The Cg Tutorial teaches you more than just the Cg Shading Language. It serves as a lucid introduction to all the basic concepts of the modern graphics pipeline – from vertices and polygons, and the building blocks of shader programming, to more advanced topics like bump mapping and toon shading. Most chapters also introduce graphics concepts first before supporting them with implementation details, making them ideal for learning computer graphics.

This resource is now available here for free in HTML on the NVIDIA Developer site.
