Ah, do you mean that using rectangle textures is only a coordinates thing and doesn't affect the memory layout at all, and so 3840x3840 will still be stored as 4096x4096 no matter what ?


No, rectangle textures will use pretty much the exact pixel size (usually the row packing is rounded up to the next 16 byte value for efficiency).

I said you need 1GB because that is the closest value one can actually buy.  2GB would insure no paging to disk or out of VRAM though.
