Bishop7319:
I have tried everything I can think of to stop the jerky motion of the meter bar.
Any advice?
If the meter doesn't play smoothly on your computer, something, other than the WGT game client, is likely using up to much of your computer's CPU performance.
It could even be that your's and KingSak's CPU or your power supply are running hot because you need to clean the heat sink around the CPU in your computer case and the inside of the power supply.
With Task Manager open, set to Performance, and minimized to your task bar you can monitor how busy your computer's CPU is during the swing. A pause at the top of the swing for a 3 or 4 count is usually needed to let the CPU performance dwindle.
Check your StartUp list and disable everything you don't need to play WGT that might run in the background as you try to play WGT.
