Bluetooth Stutter

Some users may notice that their machines suffer from stuttering issues with Bluetooth devices. This issue may occur in the form of a jumpy Bluetooth mouse, or poor quality Bluetooth audio, or other Bluetooth problems. Some users have noted that this is worse when using their wireless adapter, but this is not always the case.

Unfortunately, this is an issue that has been a hot button issue for Windows 10 since launch, and Microsoft has not meaningful addressed it as of Windows 10 1809 (October 2018 Update). Some machines are affected more than others, but the issue boils down to Windows 10 handling DPC interrupts poorly. It is not specific to your network adapter, Bluetooth adapter, machine manufacturer, or Bluetooth device. Here are a few examples of some searches that highlight just how widespread and enduring this issue has been:

As you can see, all Windows 10 systems, devices, versions, and applications are affected. Until Microsoft fixes the issue with Windows 10, there are a few things that you can do with your specific system that may help. These are things that are just good ideas in general, but people have reported that they have also helped with this problem.

  • Make sure your machine’s BIOS is up to date.
  • Make sure your machine’s chipset drivers are up to date from the machine manufacturer’s support page.
  • Update your Bluetooth and Wi-Fi adapter driver from the manufacturer (that would be us if you have a Killer Wireless-adapter)
  • Download and install all other driver updates from the machine manufacturer, even if you don’t recognize them. If they are not applicable, they will have no effect.
  • If your machine uses Intel and Nvidia graphics, try stripping the Intel driver by using our guide to clean-install any driver in Device Manager, then install only the latest package. Click here for our guide to clean-install any driver.
  • If your machine uses Intel and Nvidia graphics, and you have your computer plugged into a wall outlet, try disabling the Intel graphics. Using only your Nvidia graphics adapter will cause an increased drain on the battery but may help with this issue.
  • Increase your graphics to maximum performance. This setting will increase battery usage. You will need to refer to the support for your graphics manufacturer (Nvidia, AMD, or Intel)
  • If you have an Intel CPU, download Intel’s update manager from their website and check for updates.
  • Avoid using Wireless-N 2.4 GHz, if possible, as it can directly interfere with Bluetooth.
  • Try changing the Wireless-N 2.4 GHz channel on your router, even if you aren’t using it, as it may have an effect. If you do not use your 2.4 GHz wireless access point, consider disabling it. You will need to refer to your router’s support documentation for instructions.
  • If you have the option, disable your Wi-Fi adapter and use Ethernet. Wi-Fi adapters have high DPC latency by nature, so they contribute to the issue.
  • Make sure Windows is completely up to date. To do this, click Start, type Windows Update, click whatever Windows Update entry appears (Windows Update Settings, etc.), click the Check for Updates button, and wait for any updates to install. Once complete, restart your computer by clicking Start > Power > Restart, then repeat the steps to check for updates. Do this until there are no Windows Updates upon a fresh restart and you will have the latest version of Windows 10.
