>>2098242> is this something that cannot be controlled once a vector has been rendered into an imageDepends on how it was exported, if any effects were applied and also what screen you're viewing it on. Technically, as soon as it has to be rasterized for screen display, any mathematical curve is going to translate to a bunch of pixels. It all comes down to what you can tolerate. Sounds like ultra HD is you best bet right now.
I'll attach a wallpaper I made recently that I think might qualify for example. I don't think it was "perfectly rendered" but it might be good enough. Otherwise, that's all I know, hope that helps.
