Is THIS your laptop?
You really should not be having hardware issues with that.
Do check what is running in the background as that will suck up CPU and RAM.
Because the problem is intermittent, it would point to a network loading issue. The only way to get around that is to slow down your play.
EG.
Select aim, club, spin, etc. and then wait about 5 seconds.
Pause at the top of your back swing as long as you can.
This allows the information to be sent to the WGT servers and return before your swing so you are not receiving packets during the stroke.
