How's the latency? I've had to keep using xterm even though it kind of sucks just because it's got the lowest latency by quite a bit.

According to this (at least 11 months old) benchmark, Ghostty has the worst input latency across all contenders: https://github.com/moktavizen/terminal-benchmark?tab=readme-...

14 months old discussion of input latency in Ghostty with comments from the author: https://github.com/ghostty-org/ghostty/discussions/4837

I'm generally very sensitive to input latency and there's no way Ghostty has 41ms. I've only been using it for a couple of months though, so I guess it's fixed now.

Edit: just saw your second link from 4 months and yes, it's now avg 13ms which feels about right to me. Not perfect but acceptable. So what's even the point of sharing the old benchmark?

I don’t type more than 100 characters a second so I’ve never ran into bits limits.

I have been using computers and terminal for a long time, and this kind of comment makes me think I must have missed a whole bunch of things which can be done with a terminal

[kccqzy]

Since people are mentioning latency I’ll mention throughput. Basically the idea is that you accidentally cat a large file to your terminal and we are measuring how much time it takes for the terminal to finish displaying it. This test generally favors GPU-accelerated terminals.

Ghostty performs very well on this regard, among the same league as Alacritty and Ptyxis.

Rather, what will win is a terminal that internally builds an efficient, symbolic representation of what is on the display, rather than a pixel representation with all the font glyph, and which efficiently sychronizes that symbolic representation to the graphical canvas, skipping intermediate updates when the abstract display is changing too fast.

Have you tried kitty with more aggressive settings? It feels very responsive out of the box, but the defaults are balanced for sane energy use on portable machines.

  repaint_delay 5
  input_delay 1
  sync_to_monitor no

on my machine, noticeable. I seriously tried it, but went back because I could notice a small end-end latency, between keypress and action. But I'm also 240hz user.

[kazinator]

Where are you measuring the keypress from? The nerve signal to your finger muscles?> Or the time the keycap hits bottom? What if the switch closes before the cap hits bottom: then we are getting a latency figure that looks better than it really is.
