I noticed the update to 4.0.1.1 after I had rebooted my PC with BI4 on it this morning for a Windows update. Looking right now from the BI app on Android it's showing 62% CPU usage. But I also know that this usage listed does not reflect the number of cores in use. Most of the time my PC is only using one out of the four cores. BI4 and the app only shows the CPU %, not the number of cores in use. It could be 65% with one core, two cores, three cores, or four cores. I run the Intel Extreme Tuning Utility program in the background that shows me the cores in use. As well as memory, CPU temps etc. And the recent averages of each one it keeps track of.
