Terminal dispensed with NSScrollView and I think that won a performance advantage in rendering. It's hard to do if you're not Apple. They also modulate the refresh rate based on load, which 3.1 adds. They're using Core Text which is very slow compared to Core Graphics but they made it up with clever hacks.
- mikejmoffitt 10y agoI don't buy it as the main problem. 60fps is not asking for very much from a terminal emulator. VGA text modes can handle it, my old 486DX laptop can handle it, and XTerm can handle it (even fully software rendering everything to a buffer). It's possible core text is to blame, but this seems like an odd problem for an emulator to have in 2017.
