Should You Use Motion Sync on Your Gaming Mouse?

Many top-end gaming mice now offer the option to use Motion Sync, a feature that synchronizes SPI reads with USB polls to reduce jitter and improve sensor responsiveness. This has sparked a debate among gamers as to whether it’s worth enabling this feature or not. In this article, we’ll explore the advantages and disadvantages of using Motion Sync and determine who can benefit from it.

What is Motion Sync?

Motion Sync, when implemented correctly, promises a more consistent and smooth sensor response by syncing the signals your mouse sends with the intervals your PC polls for that data. This can result in improved tracking and a smoother cursor movement both on your desktop and in-game.

What mouses have motion sync?

Motion Sync is a feature that is commonly found in gaming mice equipped with PixArt sensors (e.g., PixArt 3370-3395 or their equivalents). Some of the gaming mice known to have Motion Sync include:

  1. Razer Viper Ultimate
  2. Razer Basilisk Ultimate
  3. Logitech G Pro X Superlight
  4. Logitech G502 Lightspeed
  5. Glorious Model O Wireless
  6. SteelSeries Aerox 3 Wireless
  7. Pulsar X2 (with Fusion software update)

The Downside of Motion Sync

While Motion Sync can provide a more consistent sensor tracking experience, it does come with a trade-off. Enabling Motion Sync adds a 1ms input delay, meaning there is a slight delay between your mouse movements and the corresponding action on the screen. This delay may not be noticeable for most gamers, but if you’re playing competitive tac-shooters like CS:GO or Valorant that require precise aim, it could impact your performance.

Who Benefits from Motion Sync

In general, enabling Motion Sync on your gaming mouse is a good idea, as the benefits of reduced jitter and improved sensor responsiveness outweigh the 1ms input delay. However, if you primarily play competitive tac-shooters where consistent tracking is not as crucial, it might be worth testing Motion Sync and determining if it negatively impacts your aim.

For gamers who play tracking-heavy games, turning off Motion Sync doesn’t make much sense, as modern mice with well-implemented Motion Sync technology offer excellent precision and responsiveness.

How to Check if Motion Sync is Enabled

If you want to check whether Motion Sync is enabled on your gaming mouse, you can use a utility like Mouse Tester. Collect some data using the utility and observe the xCount vs. Time graph. If the polls are consistent and aligned with your set polling rate, Motion Sync is indeed enabled. If the polls are irregular and not synced, Motion Sync is likely disabled.

Should you turn it on or off?

In the majority of cases, running Motion Sync on your gaming mouse is a beneficial setting that improves cursor precision and sensor response. Unless you play competitive tac-shooters where even the slightest delay can impact your performance, keeping Motion Sync enabled should be the default choice.

Note: This article assumes that Motion Sync is a hardware-based feature in the sensor of your gaming mouse. If you’re uncertain about the specifics of Motion Sync implementation in your mouse, it’s recommended to consult the manufacturer’s documentation or reach out to their customer support for clarification.
