Im sure he is doing something clever: On my Athlon 3200+ W2k system, with QPC2 running at the "lowest" priority (but not Idle) in the background and with Power saving switched off, CPU usage lies at around 97-99% most of the time (while Im watching, anyway!) Still, theres no noticable slowing down of the system. On my 1.2GHz WXP notebook, with priority set to Idle and Power savings mode switched on, it stays at around 1% most of the time while "buttonised", jumping up to 20 or 30 occasionally. However, if I get Qpc2 to do something, like run a simple loop in Sbasic, it wizzes up into the 90's.
