Set timer resolution7/5/2023 However, it to to specify the resolution in 100 ns units. Note: This call is similar to timeBeginPeriod. Note: The supported resolutions can be obtained by a call to NtQueryTimerResolution() The requested resolution in 100 ns units: after loading NtSetTimerResolution from ntdll.dll: #define STATUS_TIMER_RESOLUTION_NOT_SET 0xC0000245 The supported resolutions can be obtained by a call to NtQueryTimerResolution(). Modern hardware does support 0.5 ms resolution.Įven more details are found in Inside Windows NT High Resolution Timers. Nevertheless, the true achievable resoltion is determined by the underlying hardware. See How to set timer resolution to 0.5ms ? on MSDN. For me this makes the difference between 35 FPS and 60+ FPS on an I7 4790K and R9 290. Run the game WITHOUT Geforce Experience / AMD Gaming Evolved. NtSetTimerResolution is exported by the native Windows NT library NTDLL.DLL. Download the free version of TimerResolution.exe Open it and set to maximum. 0 seconds of 1 minute, 13 secondsVolume 0 00:25 01:13 Alternatively, you can press the Windows button on your keyboard. If the taskbar has been moved, the button might be found on one of the other edges of the display. Just checked this one, nothing changed in Windows 10 10240 build, but as it is 10240 build, not TH2, so we might need to wait before we know did it changed or not.You may obtain 0.5 ms resolution by means of the hidden API NtSetTimerResolution(). To get started, click on the Windows button located in the bottom left of your desktop. Yes, but software can apply the timer resolution, and when multimedia software are running and using some API, the Vista Multimedia Scheduler(as you can see inside the Process Lasso - Options - Tools) will set the timer resolution, but it seen like this registry settings has been not used, because the timer resolution still the same.Īnd yup, the overhead has been greatly reduced in Windows 8, but still no one doing research on Windows 10 TH2, so I guess we need some time to know why Windows 10 change this behave to a much lower value/timer resolution.

This is also the same for Adobe Flash Player(NPAPI) and MPC-HC(it will keep as 0.500, as MadVR is keep running while pausing.), unless you are running Edge or IE, which always running 15.6 milliseconds for better power save.īut it has a issues, you can't see it when you has run powercfg /energy, it will not showing any game/multimedia running and set 0.500 milliseconds timer resolution for them, and the current timer resolution is showing as 15.6 milliseconds. I also tried Planetside 2, and it is also having the same behave, just it will jump back to 1 milliseconds as the game required it. When the driver calls the ExSetTimer routine to set. Determining Windows Timer Resolution With PowerShell. The Packet Scheduler cannot schedule packets for transmission more frequently than permitted by the value of this entry. and NtSetTimerResolution(), NtQueryTimerResolution() for process. Moving away from theory let’s look at some code to determine what our current timer resolution is, and modify it to give us better accuracy. Set timer resolution Determines the smallest unit of time that the Packet Scheduler uses when scheduling packets for transmission. To create a high-resolution timer, a WDM driver calls the ExAllocateTimer routine and sets the EXTIMERHIGHRESOLUTION flag in the Attributes parameter. Can we change the Windows timer (ticks) resolution from the default value. It is also because when I am running War Thunder, it will not set any Timer resolution in the Hanger, and thank for that, I found that it is dynamic apply in TH2 now. Thus, drivers should use high-resolution timers only when timer accuracy is essential, and use default-resolution timers in all other cases. Yup, it is much more better, for now, it is 0.500 milliseconds as default(1.001 millisecond when it is build 10240), and only apply when the thread is running and needed.
