This only started happening with the new update and on the PTR, for some reason when I enable sound it tanks my FPS to 6-15 from like 120. When I open the sound menu it constantly makes a clicking sound like an option is being selected over and over. Disabling addons didn’t fix it.
Disabling sound in the menu resolves the issue, but obviously this disables all sounds from the game. Turning it back on brings the issue back regardless of which output device I choose. I don’t think changing any of the other settings had any affect on it.
