In my experience, keying the K3 from the PC works perfectly when an actual
hardware serial (com) port is used. I've used 3 different computers since
I've had my K3, including an old Compaq laptop used just for Field Day.
The stuttering comes from (maybe) the OS handling for the USB side of a USB
to serial converter. So far, I haven't found any USB to serial converters
that don't have that problem, although others people insist they work fine.
So maybe performance varies with OS loading.
I used a homebrew SO2R box this past weekend for the CQ WW CW. The box
includes a USB to serial adapter implemented with custom code running on
a USB capable microcontroller chip. This particular USB to serial converter
stuttered only about 10 times over the process of logging 2800 QSOs.
