I think that people are confusing a couple of things on this thread, so her=
e are two statements of fact:

- After Effects has an internal limit of 2GB for a single image frame held =
in memory.
- The ray-traced 3D renderer will use all of the VRAM on a graphics card (e=
ven more than 2BG, e.g., 6GB).

A detail about that second fact is that the renderer will treat multiple ca=
rds as if they each have the lesser amount of VRAM (e.g., both treated as 2=
GB if one has 2GB and the other has 4GB).

Having large amounts of VRAM can help when you are dealing with large numbe=
rs of textures (such as when using an animated environment map), since all =
of them can be held in VRAM and not have to be swapped in and out.

im pretty sure that even if you have just a 4gb card the raytracer will onl=
y be able to use 2GB
