GPU acceleration would depend on the Xi frontend. I know that xi-win (https://github.com/google/xi-win https://github.com/google/xi-win) uses Direct2D and DirectComposition. DirectWrite is on the CPU, though, AFAIK. It would be cool to hook it up to pathfinder for a full-stack GPU editor, but I'm not sure it would make a huge difference vs CPU+glyph caching.
