### Standards-Compliant Terminal Emulation Additional details for each step in the big roadmap below:

### Competitive Rendering Performance #### Competitive Performance
I want to benchmark this better, but we can maintain roughly 100fps under We need better benchmarks to continuously verify this, but I believe at

terminal emulator other than iTerm that uses Metal directly. And we're the
only terminal emulator that has a Metal renderer that supports ligatures.
### Richer Windowing Features For rendering, we have a multi-renderer architecture that uses OpenGL on
Linux and Metal on macOS. As far as I'm aware, we're the only terminal
emulator other than iTerm that uses Metal directly. And we're the only
terminal emulator that has a Metal renderer that supports ligatures (iTerm
uses a CPU renderer if ligatures are enabled). We can maintain roughly
100fps under heavy load and 120fps generally -- though the terminal is
usually rendering much lower due to little screen changes.
For IO, we have a dedicated IO thread that maintains very little jitter
under heavy IO load (i.e. `cat <big file>.txt`). On bechmarks for IO,
we're usually top of the class by a large margin over popular terminal
emulators. For example, reading a dump of plain text is 4x faster compared
to iTerm and Kitty, and 2x faster than Terminal.app. Alacritty is very
fast but we're still ~15% faster and our app experience is much more
feature rich.
#### Richer Windowing Features
We support multi-window and tabbing on Mac. We will support panes/splits We support multi-window and tabbing on Mac. We will support panes/splits
