Hi,

Welcome to the forum! 😉

How many vertices do you need to draw?

If the shape doesn’t change, it might not be faster because it depends on how much time the computer takes to compute the curve points you are drawing. If you are doing an expensive computation to compute the line then yes but if you have a lot of vertices to draw it’s not the same issue.

Also it’s not entirely related to your question but you might want to read this previous thread about rendering on the GPU :

Let’s start with the problem: We’re currently displaying a map of objects (simple rectangles with text in them, plus some single lines). Unfortunately, the number elements can go up to 25,000, probably even more, which completely crushes the performance. At the moment, we do all the draw calls in the draw() function, which I assume, is the main problem. In an older version, there’s a manual check, if an objec…
