alt Hacker NewsSmooth scrolling also worked on the Amiga Cygnus Editor in 1986 - yes, 40 years ago - on a computer with 512Kb RAM and a ~7MHz 68000 CPU, and from keyboard too. And Zed complains at launch if it doesn't find a suitable Vulkan GPU driver, since the fallback CPU driver does not provide a smooth enough experience, despite 4-5 orders of magnitude more RAM, and a ~3 orders of magnitude faster CPU, than a 40 years old Amiga...
Isn’t this just a case of not wanting to or having the resources to maintain a fallback renderer?
Supporting basically-compliant Vulkan GPUs covers probably 99.9% of developer machines. You need a pretty big user base to make it make sense to support the last 0.1% of people without access to a proper GPU driver.
I hope Zed reaches that scale, since I really like the project. But right now I would be a bit disappointed if that was a priority.
