The issue was caused by MSI Afterburner + RivaTuner (RTSS).
As soon as I completely closed Afterburner and RTSS, the mouse freeze on key-tap disappeared instantly. No more first-press hitch or freezes on unmapped keys, frametime stays perfect and the input is perfectly smooth again.
Close RivaTuner (RTSS) and Afterburner completely.
i think the cause is that maybe the overlay hooks can interfere with Frostbite’s input thread even if FPS looks normal.
While closing these did help, it didn't fully erase the issue. For me it just made it slightly less noticeable while still being unplayable.
