Assassin's Creed Black Flag Resynced is a great remake of one of the best entries in the entire Assassin's Creed series. While it generally runs well on most modern PCs, some players with capable hardware are still experiencing random stuttering, input delay, or inconsistent frame pacing. While it might sound stupid, the problem may have nothing to do with your system specs and could instead be caused by your controller.

Takeaways:

  1. Could my controller be causing lag in Assassin's Creed Black Flag Resynced on PC
  2. What's the best way to fix controller lag and stutter in AC Black Flag Resynced on computer?

Can Controllers Really Cause Stutter and Lag in Games?

Wired controllers are usually very reliable as long as the correct drivers are installed. However, wireless controllers can sometimes cause input latency, polling issues, or stutters because of Bluetooth interference, outdated firmware, or unstable wireless connections. So before trying anything more complicated, check the quick fixes below.

  • Fully charge your controller or replace the batteries.
  • Disconnect any controllers or wireless devices you're not using.
  • Switch from Bluetooth to a wired USB connection. (Plug the cable in!)
  • If you have a dongle for your controller, move it away from other dongles. 2 more more dongles together can cause big problems.

If the problem goes away, you know it's a controller issue, not a hardware issue. So you can try the steps below.

The fixes below only take a few minutes and can resolve controller-related performance issues for most players.

Update Xbox Controller Firmware

I'd be guessing that 99% of people don't realise that Xbox controllers get occasional firmware updates that improve compatibility, latency, and stability on PC. Sometimes they also add new vibration effects as well.

  • Install the Xbox Accessories app from the Microsoft Store.
  • Connect your Xbox controller using a USB cable.
  • Open the app and check for available firmware updates.
  • Install any available updates.
  • Restart your PC after the update is complete.

Note: Do not disconnect your controller while the firmware is updating.

Update PS5 DualSense Firmware

Just like with Xbox controller users, I doubt that DualShock users know that Sony regularly releases firmware updates for the DualSense controller that improve PC compatibility and fix connection issues.

  • Download and install the official DualSense Firmware Updater for Windows.
  • Connect your DualSense controller with a USB cable.
  • Launch the updater and follow the on-screen instructions.
  • Wait for the update to finish completely before disconnecting the controller.

Note: Interrupting a firmware update can cause additional controller issues, so allow the process to finish.

Update Third-Party Controller Software

If you have a cheap third-party controller, you probably won't find any firmware updates available, however, if you have a decent brand or a Steam Controller, you should check for firmware updates.

  • Visit the official website for your controller's manufacturer.
  • Download the latest firmware or driver update utility.
  • Install any available updates.
  • Restart your PC before launching the game again.

Again! Keep in mind that some budget controllers don't receive firmware updates, so there may not be a software fix if the hardware itself is causing the problem.
