T. . . I have purchased a new Hp Home unit with 3 terbytes and all windows 10 upgrades with great malware protection.
I bought a refurbished Dell Optiplex 760 a couple of years ago and rarely have a jerky meter because I maintain my computer very well.
I live in rural Iowa and have a relatively slow cable modem Internet connection through a small telecommunications co-operative (ISP).
Note that the OP discovered an application running in the background that was keeping his CPU to busy (@ 50% performance) to play the meter smoothly on his computer.
Many, many other WGT players have found that meter stutter during the down swing is directly related to how busy your computer's CPU is during the down swing.
Adobe Flash was create by and is maintained, so far, by Adobe, not WGT.
By the way - a new release of Flash Player became available today and it is now installed on my computer.
