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.
