Modern laptops often have two video card. Built-in to the motherboard (integrated) and discrete - single card from a third party. Built-in video card, although its can not be weak, use RAM as the video memory.
Integrated graphics IntelHD4000 and older cards do not work properly with many programs, including our atlas. Possible crash the program when user try to turn on the labels in the interface of the working window. To prevent such problems, we advise to use a discrete graphics card for the atlas.
