Click, Pause, Rage: Terminal Wars
Terminal Latency on Windows
Windows Terminal halves lag — now the comments riot
TLDR: Windows Terminal 1.19 cuts typing lag about in half, bringing it close to the fastest Windows options. Commenters split between cheering, complaining about click‑to‑pause behavior, calling for old‑school serial support, and trolling that Windows is “a gaming OS,” proving performance isn’t the only battleground.
Windows Terminal just got a real glow‑up: version 1.19 slashes typing lag by about half, landing it in “finally fast” territory alongside fan favorites like MinTTY. The tests show Windows Terminal hitting snappy numbers, while old‑school conhost still stumbles with weird color defaults (that “pukey green” yellow is now a meme). But the victory lap? Short. The comment section turned into a street fight.
The strongest take: “Does clicking still freeze everything?” One user says they live in a “plain old DOS box” because Windows Terminal felt like it never discovered Ctrl‑S (the old pause shortcut). Another camp demands retro comforts: built‑in serial (RS‑232) support, with diehards clinging to PuTTY and HyperTerminal like it’s 2003. Then the graphics nerds showed up, arguing about NVIDIA settings and mysterious “pipelines,” claiming memory leaks and lag depending on how the terminal draws text. Cue the popcorn. And of course, someone dropped the line of the week: “Why use a terminal on a gaming OS?” Sparking a flame war between devs who live in terminals and gamers who just want frames.
So yes, Windows Terminal got faster. But the community? Divided, hilarious, and very loud. Speed helps; habits, nostalgia, and graphics gremlins still rule the vibe.
Key Points
- •Windows Terminal 1.19 introduced a fix that halves input latency, reportedly making it competitive with WSLtty.
- •Terminals tested: conhost.exe (Windows Console), MinTTY 3.7.0, Alacritty 0.13.1, WezTerm (20240203 build), Windows Terminal 1.18.10301.0 on Windows 10 (19045).
- •Feature tests found WezTerm and Windows Terminal provide color and major attributes; conhost.exe lacks color and italics; MinTTY and Alacritty rendered black-and-white with varying attribute support.
- •Latency methodology used Is It Snappy?, with standardized keypress timing and median of five measurements on a specified hardware setup (i7-4771, GTX 1060, 4K 120 Hz display).
- •80x50 window latency medians ranged from 33.3 ms (conhost.exe WSL1, MinTTY WSL1) to 66.7 ms (WezTerm WSL1, Windows Terminal WSL1); conhost.exe has noted default palette issues.
