OneDrive and cloud sync services: impact on gaming performance

OneDrive, Google Drive, Dropbox — sync clients run background processes that continuously monitor file system changes. During a gaming session, this adds overhead.

What sync clients do

File system watchers monitor directories for changes. When a file changes, the client uploads it. This involves:

  • File system filter driver (adds overhead to every file open/close)
  • Background network upload (consumes upstream bandwidth)
  • CPU processing for change detection and delta computation

The gaming impact

In most cases: 1-3% CPU overhead from the filter driver alone. Network impact depends on whether files in watched folders change during gaming (save files, screenshots).

More significant on lower-end hardware (4-core systems, older CPUs).

Pause sync during gaming

OneDrive: right-click tray icon → Pause syncing → 2 hours.

Google Drive / Dropbox: similar pause options in their tray icons.

Permanent fix

Move your game install directories outside of synced folders. Steam library on D:\Games rather than inside Documents or Desktop (which OneDrive syncs by default).

Disable OneDrive startup

If you don't use OneDrive:

reg delete "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run" /v OneDrive /f
Enter fullscreen mode Exit fullscreen mode

Or: Task Manager → Startup → OneDrive → Disable.

Backup alternative

Use Windows Backup or a scheduled script to backup important files instead. No continuous overhead.

IzanagiOP removes OneDrive from startup and disables its background activity. https://terweb.lt/
