I'm assuming you mean integrated video from your main CPU, with it being able to have a max of 1 GB allocated to it.

The scanner will run with integrated video, I was doing so on my laptop with success, but I haven't tested to see if the limits of graphical memory behave the same with that setup. At best, you will be restricted to a somewhat small object. As long as you do not have to manually align, you will likely be able to scan for a little over an hour, or 50-60 scans depending on how much data is picked up per scan, before the software is highly likely of crashing.

Monitor your graphical memory to be able to predict instability, even if it does happen at a lower amount than 1 GB, it will be very consistent. This will have to do until they release a new version of the software with the ability to save your project.
