Let's say that I want an area of 128x128 to be a solid color. Would it be more efficient to:
Make a sprite 128x128 (white, then I would change the overlay of each instance as needed)
Make a 2x2 (Basically a small image) as a "Tiled Background" and stretch it out to 128x128?
Make a 2x2 "Sprite" and stretch it out?
Which solution gives the best performance- saving VRAM without sacrificing rendering speed, etc...?
