How much video RAM does 3D Sensations require?
3D Sensations’ effects require a 3D graphics accelerator that has a minimum of 4 MB video memory onboard. You may require more video RAM in your 3D graphics accelerator, depending on the display resolution you want to use. A general rule of thumb is that the higher the screen resolution, the more video RAM will be required. For example, 640×480 and 800x600x16 can generally be rendered with 4 MB of video RAM, whereas 1024x768x16 will require 8 MB of video RAM.
