The only way to find out is to try it…
There are a few ways to draw lines, I was just suggesting one. It can also be done entirely in a fragment shader. Here’s a SVG test in a shader: https://www.shadertoy.com/view/llySWc
I don’t think drawing smooth lines on GPU is a problem these days.
What I’m intrigued to know, is whether the multi-threaded rendering calls will work more smoothly with the host DAW, or not.
