Hi Magic, First, this has been most helpful, keep up the great work! Second, I currently have 18% cpu usage due to hardware interrupts and dpc. Using process explorer and latencymon I figured out it was due to Nvidia driver and Intel Management Engine Interface. I updated both drivers (nvidia 266.77, 275.33, 280.19, 266.44)(MEI 7.0.0.1118) but the problem persists. Trial and error has given me these results: Both Nvidia and MEI enabled: 18% Nvidia enabled MEI disabled: 16% Nvidia disabled MEI enabled: 6% Both disabled: .08% I can live without the MEI but I am an avid gamer and need the graphics card! The card is an MSI GTX 560ti. Any thoughts on what I should do next? I plan on putting in my old GTX 260 and seeing if it's not the drivers themselves but the actual card. Edit: CPU usage is at 19% with GTX 260 >.<
