3840x3840 = 14,745,600 pixels

Each pixel is 4 bytes so 14745600 * 4 = 58,982,400 bytes

16 of those would be 943,718,400 bytes

The textures would probably not fit on a 1GB GPU since the VRAM is also used for the display buffers too.

hey,

this goes on...
if i make a grid 16 squares, each with a different 3840x3840 texture.
how much system RAM i need and how much GPU ram?
