Truth forvmy side not sure. I haven't upgraded to piplay 3.0 yet. What is the version number of piplay?
@Pimax-Support might be able to did deeper by setting up a Skype with teamviewer.
Now you did say that it seems to affect your pc when headset is disconnected from your pc. Typically myself I exit piplay completely & only run it when i want to use the headset. That way its not using resources when not in use.
EDIT mixing your post with another user.
Skipping video @jonnypanic might have some ideas as i know he also has a 1060 3gig gpu.
