>>This is what I cannot understand. Can a wireless bluetooth keyboard be really causing latencies like that at the PC level in general?
Who knows what happens in the depths with IRQ, interrupts etc etc... maybe worth resuscitating an older USB keyboard to see if that resolves it.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
