For 1), aren’t there two gpu-based terminal emulators on that list with under 16ms latency on a 60Hz display. I think that should mean less than one frame but I don’t really understand the lack of variance in the measurements. I think if reported latencies are very low, the software methodology doesn’t work so well.
Am I missing something?
- DiabloD3 3y agoThe only other GPU accelerated one I see is Kitty. Current Alacritty numbers are closer to Kitty than rxvt. Kitty statically renders at 100hz, thus skews numbers a bit; however, this also proves all this guy measured was "time to next frame", not actual performance numbers.
- mrob 3y agoKitty is capped at 100fps by default, but you can speed it up at the cost of higher CPU usage: https://sw.kovidgoyal.net/kitty/conf/#conf-kitty-performance https://sw.kovidgoyal.net/kitty/conf/#conf-kitty-performance
- kragen 3y agoin the ideal case where every keystroke shows up in the next frame you should get an average of 8.3ms on a 60hz display, with a range from 0 (i did say this was ideal) to 16.7ms
