The Rive renderer takes an animation-first approach to all path rendering, including text. Meaning, every glyph is redrawn from raw bezier curves with full precision antialiasing, every frame. (Just like any other path.)

This optimizes the smoothness of animation, is fast enough to render fullscreen pages on top of pages of high dpi text at 120fps (on a decent GPU), and the antialiasing quality is always full precision in the (0..255) color channels.

If you want more niche text-specific features like hinting and clear text, those aren’t supported because they don’t animate smoothly and/or don’t work as well with colors other than black and white.

I recommend trying all the options for your specific needs and finding what works best!
