Hi hsk, you will probably only notice a difference if you try to render a scene which uses many different textures (i.e. so many textures that they exceed the onboard memory of the 1.5GB card). Once that happens Lumion will attempt to use the system memory and your harddrive to temporarily store the textures in your scenes, which in turn will cause a slow-down. A 3GB card, however, will enable you to create scenes with a lot more textures before Lumion needs to use the system memory/harddrive as swap space.
