UPDATE: i found out exactly what the problem was...the sound...in the settings there is a slider that you can use to choose the number of tracks that the world plays at any given time, and i had to cut it down to 4...it was at some insane number like 150+...so maybe if i had a proprietary sound driver for this PC in linux format, then it would not shutter as much, now the problem is gone, but a better driver would certainly enable better handling of the sound without cutting it down to bare minimum...
the ticket i opened up is here for the devs so they can point people to it later if they need to:
