[UPDATE] Ubisoft reached out with the following comment, essentially discounting most of the previous information shared by the Support team.
[ORIGINAL STORY] Ubisoft Support shared a list of PC applications that can cause various types of issues, such as crashes or lower than expected performance, if left running alongside its games.
The list includes extremely popular software like Discord, Skype, OBS, MSI Afterburner, and Overwolf.
The Ubisoft Support even goes as far as recommending the removal of non-Microsoft services.
Let us know in the comments section if these steps truly helped you with fixing any issue encountered in recent Ubisoft games.
Checking if a background application is causing the issue
If the issue does not occur, follow the same steps checking the next startup item on the list.
Repeat this until you come across the issue again - the last startup item you checked will be the one interfering with your game.
Please note that this process will likely lead to disabling the firewall and security software. Once you have finished testing the game, do not forget to re-enable it.
