Mitchell has a 5 min lightning talk discussing performance of ghostty which is worth a quick watch https://www.youtube.com/watch?v=cPaGkEesw20&t=3015s
It's one of those things that you don't realize how poor the performance is until you experience something better.

No, it’s one of those things I’ve tested myself extensively and arrived at my own conclusion. Which I already mentioned in the comment you responded to.
The performance talk is about ghostty, which you did not mention trying. You mention alacritty, which is GPU based and offers good performance, but you're quick to rebuttal on unrelated projects.
I can understand being frustrated about latency on older Macs — I used to run Alacritty for certain tasks on my Intel Macs for that reason. But on newer Macs like a new M4 Pro I’m back to 100% iTerm 2 again. I can’t fathom having latency problems with iTerm 2 on a new Mac you just unboxed.
