I do have the occasional meter glitch, but nothing bad and frequent enough to make me think about upgrading my PC ( not that I can afford to anyway ) or give up playing.
I don't know what type of system would play flawlessly, but I have seen posts from people with low level and high level systems complaining of meter issues. Personally, I think it is more to do with what your processor is doing whilst you are playing the game than anything else, but I have no hard facts to back that up. Just try to minimise as many unnecessary tasks as you can on your PC via the Task Manager or System Configuration but only if you know that the process you are stopping are not needed for your PC to function correctly.
