Thanks c242, In the settings of the perfermance meters 2 it shows all 4 cores as 0,1,2,3 and a second option for "all instances", there are also a few other options but I have fiddled around in there with several and can't get a readout at all. I happened to find a post in another thread where someone was having a similar problem and decided to exclude the meters from his uploaded dx themes because of it. Do you know of any situation where the meters might not function? I am running Windows 7 Ultimate and all drivers and updates installed.
