@W1zzard to be safe id recommended updating the bios to the latest and then update ME FW using MoKiChU ME FW Update from the ROG forum.
Alternatively you could use the motherboard download page to download the Asus ME FW Update tool, I'd recommend unzipping and from the FW folder manually flashing with FWUpdLcl64 -FORCERESET -ALLOWSV -F ME.BIN
I'm not sure if the Asus motherboard download page update tool uses -ALLOWSV by default, It probably does but it's not something I can test currently.
ALLOWSV does what it sounds like, allows flashing the same version, because the 19.0.0.1854v2.2 is still 19.0.0.1854, it should fail without using -ALLOWSV even if the sub-firmware is newer or different.
At least that has been my experience with prior ME versions and updates.
I expect there will be zero performance difference between earlier 19.0.0.1854 and the latest build.
Everyone else, make sure all your drivers are up to date including the Intel MEI drivers.
