Fixed by doing the opposite

[I LOVE TIN FOIL]

Issue seems completely erased by setting the base clock to 102.80mhz and disabling multi core enhancement....
(9700f, z390,) tscsyncpolicy standard.

I used to follow all guides (100.00mhz locked, tscsyncpolicy enhanced)

My question is why (or how) my "bad settings" would cause a noticeable decrease to the point where mouse movement feels almost analogue and instant.

Well in my situation when the issue doesn't exist it just doesn't exist, any settings work at that point.
Did the issue get fixed for a long time or is it just fixed atm ?
