Maxthon 3, Game Booster, clear all caches daily, clear flash weekly? get a good cleaner/ optimizer, use once a week, maybe more. Keep friends list small (Works for me, for other players, not so much.) Use the back swing hold to 3 count before release.
Any or all may help your situation. They did help my swing meter. At present my swing meter only has 1 problem and it is located on the outside of the mouse.
I play at least once a day, mid afternoon, more often, after 11 pm east coast time. On weekends during the day, and also late at night. Only problem I have had is sometimes slow to reach the site, and the frequency of disconnects is higher during the "High" volume of use periods. Does not disturb my swing meter at all.
Hope it helps. my nickle.
