Will blenders interface function with an "off the shelf" vista home, no Vid. Card?

Rendering happens on the CPU. It doesn’t matter how fast your graphics card is. The video card is used in the 3d viewports while you edit. It renders your scene there, but once you press F12 and start the scanline render, it’s all CPU.

To the original poster. Update your drivers, and try shutting off Aero. Blender runs perfect for me with my cheap video card under Vista.
