As far as I understood from the video about refterm the speedup is mostly due to not rendering literally every frame in sequence (after all, who needs that), which is what windows terminal seems to be doing.

That seems like it would be unaffected by correcting font rendering.

"... extremely slow Unicode parsing with Uniscribe and extremely slow glyph generation with DirectWrite..."

Glyph generation is about rasterising text, because you can't just feed it the font file.
