It may sound like a stupid troll like question but what ball are you using? It has been reported to WGT that the level 39 yellow Callaway is causing meter issues. I went back to the level 35 white Callaway ball and no meter problems.
ir it is not that open your task manager and see how many unnecessary programs and processes are running in the background. It might surprise you when you see just how much unnecessary stuff is running in the background using much needed resources. Close any of them that are not needed for WGT or to keep Windows running and you might be pleasantly surprised how good your meter is.
