Regarding post #9, all of this is already understood. There is nothing there that we do not already know (To the extent it is technically accurate and we know what is accurate and what is inaccurate). There is also a lot of information there that is just simply inaccurate for one reason or another. There is more work that we have been wanting to do with Sierra Chart timers, but we just have not had time to work on it but there is one easy change we can make which will probably solve the problem. And we can see that we partially started it but never finished with it. Also this is the reason why users notice, slower updates of charts on windows 11 and also charts not updating, when using the Chart Values tool or other, mouse/pointer intensive operations: On Windows 7, timer APIs were less restricted (more global impact from timeBeginPeriod, less coalescing/power management), allowing custom timers to achieve stricter intervals with lower risk of UI overload in GDI/OpenGL apps.WPA evidence (high UI delays + long UI thread running stacks during updates) confirms this on modern Windows. Many users report smoother feel with OS timers enabled on Win10/11. And we also did a review of the Chart Values tool now, to make sure no unnecessary drawing is done, when there is no actual drawing changes to show the user. We confirmed that it is already, efficient and does not do unnecessary drawing. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
