For all practical purposes, the GRAPHICS CARD is the primary resource for iClone. Therefore, it display the "VRAM" (Video card RAM) that is on your graphics card.
iClone will automatically use as much VRAM as is needed for your scene. If your scene requires more than the 3GB that's on your GPU, it will start "swapping" in and out between your VRAM and your system RAM, which will result in a huge performance slowdown.
But don't panic yet. There is a lot of animation that can be accomplished with 3GB of VRAM, and there are trick and techniques to help make efficient use of that VRAM. Just keep an eye on it, and if you start running out, come back here with a more detailed description of your scene and you'll probably get some good advice (before you need to resort to buying a new GPU with more VRAM).
But although I said "Don't panic," do understand 3GB is on the low end. So don't panic, but do be very mindful of the resources you use. Avoid unnecessarily hi4-gh-poly models and high-res textures, and remove objects that are not visible to the camera.
