Try the following to help with the Swing Meter.
-Close any and all other programs that are running. Leave only WGT on. Minimize the WGT window.
-Do not play WGT in full screen mode. Window mode runs the smoothest.
-Turn off Reflections, Flag Animation, Background Loading, Avatar rotations, and WGT Lessons in your Options
Hopefully this helps you.
