I've been playing WGT for about 2 and a bit years, so I started playing the Flash version. I upgraded to the stand alone PC version and, personally, I think the meter is better. But that is just my opinion and I respect yours, Sandriloune.
I have experienced the occasional meter stutter, but that is down to internet data buffering, in my case. That happens with any program, but is more noriceable with precision programs, such as WGT.
I'm a Master and exclusively play with the starter ball, unless I happen to win a sleeve. The only way I slow my meter down is by using apparel for specific clubs, So, once again in my case it was "toughen up, buttercup" and concentrate on my speed with the mouse button.
What is it, in your opinion that makes the meter bad? Can you be more explicit about the experiences you have had, to have you arrive at your conclusion?
