I tried it, and it worked well when I worked locally. But I can't use it to SSH into my server, a lot of things just don't work.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Finally a gpu accelerated Terminal emulator with tabbing.
Kitty has tabs
ohhh, I didnt know that thanks but Ghostty has Zero config by default which i like (Edit: maybe I might use wezterm)

I'm not against it, but another factor that we should check in a terminal emulator (as a tool where you run everything from) is the system requirements.
I'm using urxvt and that's so easy on the system, it starts instantly. I can open multiple instances without worrying about the system resources.
I believe it uses X.org's text rendering. X.org uses OpenGL under the hood. It's not CPU rendered.
Alacrity felt bulkier when I tried. I will try this too though.
Alacritty felt too slow and was missing settings I wanted (like mousewheel scroll) due to devs being opinionated. Kitty has been fast and flexible for me.
Unless it is trying to actually look cool like "cool retro terminal" or something, I fail to see how the point. I don't recall ever in the history of my terminal use ever thinking "man, this terminal emulator is so slow!" I mean, really... 120fps 4k terminals. Neat I guess?
That’s not what GPU acceleration is used for.
This. If you hadn't written it ...
4k 120 fps ?
And HDR
Nice this project was always interesting! Seems very feature rich, glad it’s out of that invite only stage
What is the deal with getting gpu acceleration into a terminal emulator of all things? Of all the innovations that we could use, faster drawing of text doesn't feel like it should be a priority.
That's what I would have said till I tried using a TUI epub reader. The jankiness of line-level scrolling (rather than pixel-level like in a GUI app) is all but a deal breaker.
I was then most surprised to discover that terminal emulators with this amazing cutting-edge technology (smooth scrolling) do not even exist.
text is like the slowest thing to draw :P when debugging games, a running log can make the 3D rendering stutter significantly.
See the minecraft f3 menu for a notorious example
no, that's just minecraft being badly made. I'm talking logs running in a separate window.
But thats different, the issue there isn’t the text drawing, its that it isn’t meaningfully asynchronous and console drawing is typically blocking (at least on windows)
that's true, but the impact would still be lessened by faster rendering. and as someone who spends all day in the terminal anyway, i do see the benefits often.
GPU rendered text interfaces are pretty ubiquitous already. You can find that in IDEs, browsers, apps and GUIs of OSs. Drawing pixels is still a job the GPU excels at. No matter whether it's just text. So I don't see a point why we shouldn't apply that to terminal emulators as well.
ok but such a sensational announcement like this suggests that before (and without) gpu acceleration the program was noticeably slow for some reason
It's not just about speed, but also (battery) efficiency.
Even if you don't notice the speed, if you are working on anything but a modern expensive laptop, you will notice the difference in battery draw between:
VS Code > NeoVim in traditional terminal > Neovim in Alacritty or Ghostty
