6/12/2023 0 Comments Set timer resolutionThanks for your thoughts Dave, and it seems like there might be something else in the background of Xojo with the timer that I am not aware. ![]() I don’t know the answer, and it doesn’t hurt to ask. My thought (which may be incorrect) is to lower the refresh rate of the global timer from 15.6 milliseconds (62 fps) to 0.5 milliseconds (2000 fps). There seems to be something that I don’t understand with the Timer in Xojo that causes flickering - which is likely below the 24 frames per second that is mentioned. The Windows computer seems to be able to have a high frames per second output, along with the ability to process and render code extremely fast. The hardware doesn’t seem to be the issue, and when using a thread can provide very fast frames per second - Here is some of the test data from a previous post: SpeedĬomputer No Mouse Movement (fps) Mouse Movement (fps) ![]() I have a 1920x1080 monitor, and the refresh rate of the hardware on an Mini Displayport using DVI is 240 frames per second, which is well above the 24 fps. Plus if your refresh rate exceeds that of the monitor you should not be able to percieve a flicker… for that matter, if your FPS exceeds even 24fps it should be hard to percieve it… since that is the retention period of most peoples eyes (and why movies were shot at that speed (on film)…digital is faster these days) Is there something that I am missing, or that can be changed to modify the default firing of the timer in Xojo on Windows? I am open to S: The default global timer limitation can be modified with the NTSetTimerResolution C command by using a Xojo Declare and an example program has been made which changes the resolution from 15,600 100ths of a nanosecond (15.6 milliseconds) to 9,000 100th of a millisecond (0.9 milliseconds) and an be downloaded here:Įxample 12-02 - Modifiy NtSetTimerResolution.Īfter running various Canvas and OpenGL examples with the lower millisecond setting (0.9 millisecond global refresh rate), there is no change with the default timer firing, and it remains at about 15.6 milliseconds instead of 0.9 milliseconds. The reason for this change is to use the timer for refreshing graphics instead of requiring a thread for firing - which causes issues with accessing Windows1 for even the most basic of changes. A time of 15 milliseconds has a maximum frames-per-second game refresh rate of about 62 fps which shows flickering of the screen. The current limitation is about 15 milliseconds (see Limitations On Microsoft Windows ). \Device\HarddiskVolume8\Program Files (x86)\Origin\Qt5Core.I am attempting to change the default resolution of Windows Timer for Xojo, and Xojo doesn’t seem to respond to this global change. \Device\HarddiskVolume8\Windows\SysWOW64\winmm.dll The Timer Resolution will let you change your default timer for the Windows PC from its standard 10 to 25 milliseconds. \Device\HarddiskVolume8\Windows\SysWOW64\kernel32.dll The stack of modules responsible for the lowest platform timer setting in this process.Ĭalling Module Stack \Device\HarddiskVolume8\Windows\SysWOW64\ntdll.dll Platform Timer Resolution:Timer Request Stack Requesting Process Path \Device\HarddiskVolume8\Program Files (x86)\Origin\Origin.exe Platform Timer Resolution:Outstanding Timer RequestĪ program or service has requested a timer resolution smaller than the platform maximum timer resolution.

If the timer resolution is increased, processor power management technologies may not be effective. If you want to change the timer resolution of your windows than you need to follow these simple steps: Download Timer Resolution. How do you set the timer resolution in windows 10 Back in the xp days you can add to the boot.ini file /TIMERES (number) can you still add this switch using bcdedit /set and if not is there an alternative you can use in wind(I tried to google it but i cant seem to find what im looking for. The default platform timer resolution is 15.6 ms (15625000 ns) and should be used whenever the system is idle. Platform Timer Resolution:Platform Timer Resolution
