Hi Scarlett,
That's great detective work! I
t’s great that you were able to identify the cause of the issue by following 2. "Check for background process" !
OneDrive can use up a significant amount of network bandwidth when it’s syncing files, which could cause high ping. You can try pausing OneDrive sync while you’re playing games to see if that helps. To do this, click on the OneDrive icon in the system tray, click on “More” and then select “Pause syncing”. You can choose how long you want to pause syncing for.
I'm glad that your ping has improved after addressing the issue with OneDrive. If you have any more questions or need further assistance, feel free to let me know.
Happy gaming!
John J.D.
