Hello, I have upgraded my PC, i5-12400 to i7-14700, but after the upgrade, MS Onenote app is not working fine, it is lagging and freezing and unable to write on it with my pen tab. But before the upgrade it is working smoothly. All other apps are working fine. Could this be related to compatibility after the CPU upgrade? Please help me with this. Any help will be appreciated.

Windows Task Manager, Performance tab, CPU will show the amount of processor utilization when using MS OneNote. What you are seeing may be caused by excessive CPU usage. Microsoft have a potential solution that you could try on this page .

Thank you for your suggestion, actually I have tried a workaround where I had installed another note taking app notability on my PC, and tried to write on it with my pen tab but surprisingly, I faced the same lag issue with it. So I think that there is an issue with my pen tab, not with Onenote or my CPU drivers.
