How do I setup a Hotkey without using so much of the CPU. There must be a better way.
HotKey Patient History.au3
Im looking to measure cpu usage thats free, and measure cpu usage of a program.
My goal is to turn intel speed step off under light cpu load.
I think I can do that, if I can find the cpu usage.
I have been using a script at work for the last 6 months or so. It gets some information from the window title and keeps it in its memory for retrieval.
currently I am running an infinite loop to look for the window title, the information in the memory is only updated if a few window title is detected.
The trouble with this approach as you can see, is the cpu usage. I was wondering if somehow I can only run this script when a windows change event occurs, otherwise the script stays dormant.
I have no idea how to do that, searched on forum and found some solutions that were years old and did not work for me.
AutoIt SysInfo Clock is a small tool in widget style to show the clock, current CPU usage, CPU speed, memory usage and network activity (tcp, ip and udp). Additionally you can use it as an alarm clock. To stop alarm clock tone press the left LED (mail) or wait 60 seconds.
The current CPU usage code is beta and might be not working for some CPUs!
Move mouse to area below seconds and press rmb to select different color scheme.

Special thanks to trancexx for helping me to read out current CPU speed using the WinAPI stuff, AndyG for troubleshooting performance counter issue, czardas for composing "Für Elise" and Ascend4nt for the support!

this is a part from my script
#include <Misc.au3> $dll = DllOpen("user32.dll") While 1 If _IsPressed("31", $dll) Then one() If _IsPressed("32", $dll) Then two() WEnd Func one() MsgBox(0, "", "1") While _IsPressed("31") or _IsPressed("61") Sleep(1) WEnd EndFunc Func two() MsgBox(0,"", "2") While _IsPressed("32") or _IsPressed("62") Sleep(1) WEnd EndFunc it is working fine but it takes 30 % of the CPU usage and it is a small simple script
when i put sleep(100) in the while loop the CPU is 1%
i think that this is a good solution but not for my case cuz the rest of my script really depends on time and 100 msec will matter
can i reduce the CPU usage without using sleep ?
