I think this just happens to fall under the category of “some people care about milliseconds of rendering time, and some people don’t.” I don’t know if the GPU acceleration has anything to do with it, but this terminal emulator also has really good font rendering.

If you are happy with your current terminal emulator, continue using it. If you heavily use your terminal emulator for a lot of things and in some things you’ve found that it stutters a bit, and you wished it was a bit smoother, get a GPU accelerated terminal emulator.

And secret bonus option: Even if you are happy with your current terminal emulator, give it a try anyway. Ghostty has a “zero configuration” policy where their goal is for most people to never need to configure anything. Sane defaults. It’s a good out of the box experience. Give it a few test drives, and if you’re still perplexed about why you should care, then maybe it’s just not for you and you can switch back. If you go “that was pretty smooth, i dont have a reason to switch back” then maybe you’ll think about it differently.
