Noticed that after leaving a table up for a couple hours, the ball becomes laggy and skips frames.
Kill VPX and restart and it's back to normal.
I looked at the initial memory footprint of VPX Theater of Magic in task manager on startup and it's around 700mb...
2 hours later... it's 1.6GB without playing a game and exhibits the ball lag.
Anyway... just putting my experience out there for the Devs.
