@nefarius OK it looks like there are still problems with my bluetooth, because both my headset and controllers are stuttering after connecting. I had previously only tested that they connected and worked, and hadn't used them since then. The headset has been tested on my phone and laptop and works without stutter there, and the controller seems to not stutter on my laptop as well. The headset is new but the controllers are old and did not stutter prior to this whole uninstallation process. The only drivers changed since last week I believe are an updated graphics card driver and those pairing with the headset. Any ideas on how to proceed would be appreciated.
