Sorry ApexPC but it is not ZR1Tom's system. Not only is the swing meter a problem but the graphics are jerking when the ball is in flight and also when putting.
This is an old problem with WGT which was rectified in 2015 but seems to have appeared again, perhaps due to the number of users on on the system.
If memory serves me well the problem was fixed last time by WGT doing something with the servers, you can tell I am not technical by my language, and the problem disappeared.
I know from my own work we have to service and maintain our servers at least once every 3 months or the system just become clogged and starts to run slow.
The only good thing about this situation is that I am saving money as only play a few holes to keep my number of days played active so no need to buy golf balls
