SDF seems to be one of the better solutions for text rendering. Valve had this problem solved since 2007. I'd argue this technique is a big part of what gave TF2 its impressive visual style. That game ran at 100+ fps on hardware like the 8800GT at the time. https://www.redblobgames.com/x/2403-distance-field-fonts/
Stupid question but what are the units used in the results tables??
This website almost crashed my m1 macbook pro (renders at 1 fps or something), so I guess point taken: rendering text is not simple!
And on my desktop, scrolling this page is painfully slow. Author: frontend technical lead, setting high code standards
Haha, to be fair it's common to half-ass personal projects even if it's your primary domain.

what's worse is that scrolling doesn't actually work unless you have the text area focused/under the wheel... very weird. Which is even worse for PgUp/Down as who would think to focus the area first for scrolling???
Sadly, this problem is common enough that click-before-keyboard-scrolling has become second nature for me.

I wonder how the GPU version is implemented. One quad and one texture draw per glyph sounds very not scalable, but one quad per terminal, one texture atlas and one shader to draw glyphs from the atlas already sounds much better.
Runs at ~1500 FPS with a 6K screen of full text on my machine even when text is being updated at about the pace of a 150 WPM typist but you only update quads that strictly need to change and store font metrics on the GPU in a buffer. A full screen refresh where you send quad data for 750 Lorem ipsum paragraphs every frame runs at 300 FPS on my hardware.

SDF is awesome but even then it's not a silver bullet. It's a raster technique and some people want vector fonts or subpixel rendering.
