It's not a daft question, tuckersj
If you use a lot of high resolution textures on a graphics card with low memory, you are likely to experience stuttering as you move the camera around in the scene in real-time. Especially if you pan from side to side, when new objects come into view. This is because the graphics card needs to load the textures on the fly. Low GPU memory may also result in 'warped 3D points' (streaks/lines of polygons).
A slow graphics card on the other hand will result in a persistently low frame rate, i.e. not a very smooth walk through in real-time.
The smoothness of camera animations is not affected by graphics card memory when rendering MP4s.
