While I can't reproduce it at-will I've definitely had occasional input problems in competitive shooter games with 6KRO + 125Hz. A depress would be processed "too late" to accidentally fall into the next window and affect movement then (e.g.: jump in wrong direction).
Yes, the key combination probably doesn't go over 6 keys at once and I don't always have ~8-16ms presses but switching over to NKRO + 1000Hz (which are coupled on QMK) would stop this from happening.
