Modern motherboards often still have a PS/2 port! And most USB keyboards still support PS/2, a passive adapter works great.
The problem is often in keyboard controller, not in the interface. Apple managed to get fastest keyboard with only 15ms lag; other may be order of magnitude slower.
Why would enforcing vsync add more than 1/60s of latency to anything? This looks way more like badly designed animations than some fundamental problem coming from the hardware.
Perhaps it ends up being multiple vsync waits for a given rendered frame? Something like the application or OpenGL driver waiting for vsync before rendering into its buffer, then the compositor waiting for the next vsync before actually compositing/flipping.
I fill that as about as likely as hardcoding the frames of animations, and displaying them all whatever device frequency you have.

Layers of abstraction take you further away from the metal. The more layers of abstraction your keypress must traverse before rendering is complete and the photons have reached your retina, the longer it will be until that happens. Layers of abstraction make complex tasks more reachable by a larger number of programmers by reducing the amount of specialist knowledge about those lower layers required to do the job. Th…
Numerous games, including those having complex graphics and behavior, can render 120+ frames per second and realtime interactions (physics, optics, reactions) on pretty average hardware. I don’t think that game scripters who make final things like scenery or ui face complexity much harder than those in gtk/qt/wpf/htmljs widget programming. Details would be interesting though, since I’m no game developer. If true, it…
The difference when it comes to why games can be snappier is that games are "allowed" to bypass most of the layers and cruft that exists between the user and the hardware, including the compositor that the linked article is talking about (in Windows at least).
Fortunately in Linux with Xorg you can get stuff on screen as fast as the code can ask for it, as long as you are not using a compositor (so you can even play games in a window with no additional lag!).
Hopefully the Wayland mania wont get to kill Xorg since yet another issue Wayland has and X11 doesn't is that with Wayland you are forced in a composition model.
> Don’t you find it a bit funny that Windows 95 is actually snappier than Windows 10? It’s really a shame that response times in modern computers are visibly worse than those in twenty years ago. My Amiga A1200 (Only have extra RAM) feels faster and more responsive that any modern computer with Windows or GNU/Linux desktop.

Try popping the start menu open on a Windows 10 machine with a mechanical hard drive.

Could someone explain to me why on earth 15ms of lag for a key press is considered good? It is a switch for gods sake. It should be near instant.

in all seriousness, why not?
The little plastic bits always snap off. Ethernet is great for semipermanent wires but not very good for peripherals like portable hard drives that are constantly disconnected and reconnected.

The obvious ones: Ethernet cables are big (imagine one on a phone), and aren't designed to be plugged and unplugged the massive number of times that USB cables are (spring contacts wear out, little clips break).
Outside HDMI and some DisplayPort cables, all display connectors click or screw in
And we’re talking about desktop OS and displays
Every additional option (especially in the realm of video settings) opens the door for additional complexity, implementation error, and user error in unintentionally setting the undesired mode. It's perfectly understandable why window managers would settle on one or the other of two extremely different render-to-screen approaches, especially when general consensus for quite some time now in the graphics space has been that minimizing the potential for tearing is preferable.

I don't claim that 15ms of lag is to be considered good, but the problem that one has to solve is debouncing the switches.
