I also experience more meter stutters in the RG's than normal.
I deal with it as best as I can, but besides a few OB shots here and there and a couple of really ugly putts, I've been able to work around it, post solid scores, and win a few RG's. I figure if everyone else is experiencing it, then we're all playing on a level playing field.
edit: I don't know if it's just coincidence, but it seems I experience more meter stutters when I play my normal fast paced game. I usually try to slow things down when I play the RG. In other words, I'll let the hole load, and then sit there for a few seconds (and sometimes a few minutes as I'm usually watching TV while playing) before doing anything. I'll wait for the flashing graphic under my username in the corner to do it's thing before I'll start my swing. And the other thing I'll do to try and reduce the stutter is when I release the mouse button to start the downswing, I make sure I don't move the mouse at all during the downswing.
