If you encounter a situation where your screen flickers or shakes while playing the game on Windows 10, please check the following workaround:
1. Head to the File Explorer and find the directory of your game. The default directory should be: C:\Program Files (x86)\Ubisoft\Assassin's Creed Revelations
2. Once you are in this folder, find the systemdetection.dll file. Rename this file to systemdetection_0.dll
3. Relaunch your game.
The issue should now be fixed!
