What is the fastest / most efficient way of creating solid rectangles with rounded corner. I don’t mean what way is quickest to implement, just what way runs fastest, least amount of frame time. This is because I wanted multiple rectangle with round corner and so it would be lag. Polygon is fast, and what I did try was 2 polygon rectangles, and then having a point on each corner which is fastest way to render a circle, but I do not believe scaling the points to remain consistent no matter screen size is possible.
