Windows System Timer Tool

Little tool to check and modify the windows system timer.

If you want to know what this is about, you should read this article:
Windows Timer Resolution: Megawatts Wasted

The matter is in my opinion less dramatic as the author of the article states, but he has written down a comprehensive collection of facts about the windows timer. Excellent article!

Source code is here:https://github.com/tebjan/TimerTool

Verison 3 minimizes to system tray and can be started with command line arguments "-t peroidVal" and "-minimized". e.g. put a .bat file into your autostart with the following code:

C:\PathToTool\TimerTool.exe -t 0.5 -minimized

Version 2 can set 0.5 ms as timer resolution.

If you like it: Donate some dev bucks, thanks a lot!

had to use this in my .bat file to get running.

start "" "C:\PathToTool\TimerTool.exe" -t 0.5 -minimized

So by default the tool tells me 0,5. I'd however like to change it to 1 but everytime i do set it to 1. It flashes up as 1.00092 for a second and then straight goes back to 0,5. Any idea how to fix this ?

@marcelxvi there might be another software running that checks the timer and sets it back to 0.5. so you need to disable all running software one after another to see which one is setting the timer to 0.5.

what windows are you using?

@tonfilm I'm running windows 10 anniversary update. Actually I've booted into safe mode and the timer was 15 and I could set it 1 just fine. Must be some software then. Can't figure out which at this point tho :/
