I’d like to point out that I’m currently having these issues as well from the latest update.
Tobii EyeX Interaction is causing some major slowdowns in windows. The start-menu is sluggish, moving windows around is sluggish, playing games is a real pain and I’m forced to execute it in order to enjoy anything. This only happened recently with the update and with the new menus in the tray and so forth.
Before that, no issues whatsoever. This is on Windows 10 64bit, desktop computer. I can send you the DxDiag if that’s of any help as well, and possibly try and get a recording of the behaviour.
