Hi,Scott, I too have had similar problems, but I assure you it is a local problem. What browser are you using? Obviously try changing browsers if it continues.
I have had a few severe meter jumps recently just as I have hit, resulting in OB's and nothing more frustrating but here are a few tips.
Clear browser cache and flash caches. Also look at your processes while playing.Many love using Maxthon for WGT and the great thing is it has a CPU meter inbuilt. Options like Tanti Meter are an alternative. If the CPU is higher, wait till it drops. Also Game Booster 3 or the like monitor what processes are being used and have the option to kill them while playing. Obviously you are better off to have no other programs running when playing. Note a dedicated browser for WGT is reccomended.
One of the most common problems are virus scanners. often running in the background. If you use Norton it will kill your meter (and computer for that matter)but it is possible to put them into game mode usually.
Hope some of this helps smoothe your meter
