Timer Resolution is a tiny and lightweight software application that is very popular among Windows gamers and some users. Many game players want more FPS ... thus increasing the time resolution they consequently improve the FPS for the games they are playing. The gaming experience may improve dramatically to the best with only one catch: the power consumption increase too. The reason that the Windows default time resolution is not set too high as default is the concern for power consumption which is a global policy against the waste of power resources. But finally it is your decision to use it or not, to increase your FPS in a game by changing the time resolution or not. Especially for the advanced gamers that can have higher resolutions this application can make a difference.
Increasing time resolution - the power consumption increase. But apart from environmental impact of wasting power resources or draining too fast a laptop battery perhaps on desktops and in the world of some advanced and passionate gamers, increasing the resolution of the timer for such purposes can make sense a lot. Actually Microsoft does not forbid increasing the Windows time resolution as it can be changed programatically it is not a hack, it is a hidden feature only.
This software application is free, open source and is written in
C#(C Sharp). You can download the binary release or you can compile it from source code, at your choice.
- being developed in C# and with dependencies on .NET SDK it offers maximum stability and compatibility with Windows platform
- application is lightweight, runs with a small amount of memory and a low footprint
- it is free and open-source, the source code can be audited by anyone
- it offers both: a light and a dark mode for the GUI
- the GUI looks a bit raw, needs some more polishing, but taking in consideration that the application is relatively new the expectations may be too high at the moment for having a very fancy GUI ...
Open Timer Resolution is a GUI native Windows software application - free and opensource - that offers the option to change the current time resolution in Windows among other options available.
- Change the resolution of the Windows System Timer
- Use Light or Dark mode for the GUI
- Log the actual resolution of the Windows System Timer, then save it into a .log file
- Enable / Disable the Memory Cache Cleaner automatically (specified in the config file, default to TRUE)
- Can run minimized at startup ; running the program with the -minimized argument will start the program, force the timer resolution (specified in the config file, default)
- Silently install the start-up schedule (if not already) using the -silentInstall argument, and start minimized
- Automatically Updates (with prompt): it will automatically check for new versions available on GitHub at startup (not using any external sources)

FAQs - Frequently Asked Questions regarding the timer resolution on Windows operating system
What is the default timer resolution in Windows ?As specified from Microsoft Windows, the default time resolution is set to 15.6 milliseconds.The common reasons for changing the default time resolution on Windows can be various: gaming and other software that may require higher time resolutions, but keep in mind that increasing the time resolution will also increase the power consumption which is
not environmentally friendlyspeaking in terms of Sustainability as a societal goal for planet Earth.
What is the minimum interval between system clock ticks ?The minimum interval between system clock ticks is about 1 millisecond.The expiration time of a default-resolution timer (which
ExAllocateTimercreates if the
EX_TIMER_HIGH_RESOLUTIONflag is not set)
can be controlled onlyto within about 15 milliseconds, but the expiration time of a high-resolution timer
can be controlledto within 1 millisecond.
How to use maximum time resolution automatically ?This can be achieved in several ways: use a dedicated software application like this - Open Timer Resolution - or set manually.Setting the time resolution using the Open Timer Resolution software application is very easy. You just download the application and use the GUI to set the desired value.To set manually, without using a dedicated software application, can be done by advanced users via
administrative templates under the computer configurationas:
Group Policy Editor (gpedit.msc) -> Network -> QoS packet scheduler -> Set timer resolution -> Enable -> Set to zero (0).
