I've tried every "accelerated" terminal app that I see, yet I find I never perceive any improvement in response, only the negative effect of losing the helper UI of menus and such compared to my (now ~10 year usage) usual term of Sakura. Kitty came closest to being usable for me, but still it involved throwing away ease of access to various things to have a boost to performance that was only something I was told I was getting, not something I was experiencing.
