What the tweaks do

Raises the scheduling priority of the audio threads, so on a busy machine they are less likely to run late. The buffer, and so the latency, is unchanged.

Work Windows starts on its own and never shows anywhere. None of these lowers a buffer or a timeout Windows provides; each either turns a switch off or raises a restriction.

The display-driver timeout back at the Windows default, and the window and taskbar animations turned off. What either does to the frame rate has not been measured.

Bigger report queues for the mouse and keyboard drivers, a shorter freeze when an input hook hangs, a shorter key-repeat delay. None of them makes a click arrive sooner.

One setting: puts Windows services back into shared svchost processes instead of one process each — fewer processes and less memory, at the cost of crash isolation between them and per-service figures in Task Manager.

What each box on the Internet page writes, what it leaves alone, and which of them can change a match — most cannot, and the page says so.

Work that starts by itself after sign-in or in the background while you play, and restarts that land mid-match. Turning fast startup off makes boot slower, not faster.
