Division 2 on Stadia runs really well, after about one hour the game degrades into 20 - 30 fps. Quitting and reloading the game fixes the issue for another few hours. Also going into Ubisoft Connect and back to the game fixes the issue.
It was documented here https://forums.ubisoft.com/showthread.php/2303751-Ubisoft-Connect-causing-performance-degradation-on-all-Stadia-Ubisoft-games?s=774b0cbc02c9edf996c0bcaeebf27883 and it's still not fixed. Any updates on this?
