I was about to quit recently due to horrible meter performance.
I basically went from about 40 friends to zero and noticed a lot of improvement @ first. After a while, the usual slow camera changes and delayed club/shot selection would occur followed by unplayable meter action.
I did the "system config" cleanup discussed in this ancient thread following YankeeJim's advice.
I also started playing (just today) through chrome's comodo dragon browser.
These last steps are pretty recent, but my meter has been almost flawless since.
good luck all
