Ok, I gotta share this, because I dealt with the stupid swing meter stutter for two months. My swing meter stutters on google chrome, so I tried firefox. The swing meter was great, but the game lags. Gotta move your cursor around on the screen to see it play like if you're watching a video. These problems are conistent, as I've rebooted multiple times. So I'm like, what other browsers are there? Internet explorer? I haven't used them for 7 years, but I thought "What the hell?" It's perfect on the swing meter AND the game play. So give it a shot (pun intended) if you haven't already!! :):)
