i honestly don't get why people think ghostty is fast. the gpu acceleration slows it down. maybe i push my machines harder than other people but when the machine is under load either gpu or cpu ghostty starts lagging super hard vs iterm. i've never had a problem with iterm render speed, but iterm never starts lagging when my box is fully maxed out and ghostty does regularly. i try it every few years and ive never seen any improvement.
