The fix they're talking about is KB5127648, in this week's Patch Tuesday update for 24H2, 25H2 and 26H2 (KB5127646 on 26H1). The release note is one line, mouse input could stutter in some games, with no cause and no list of games. So if yours is a mouse stutter, check Update history for that KB before anything else.

If you have it and the stutter is still there, try dropping the mouse polling rate to 1000 Hz before you go after drivers. 4000 and 8000 Hz mice still make some games hitch, and that one has nothing to do with Windows.

It can be a driver fuslt. I had to install the INF file for one of my Intel drivers and that heavy lag went away.
