I tried to play multiple video games using Parallels on Mac, with an install of Windows 11. Rocket League works fine, but Portal, Portal 2, and Attack On Titan 2 all suffer from the same problem: the camera view is spinning as if I move my mouse 1 meter when I move it 1cm. See video: I have found out that if the mouse is placed very much near the center of the screen, the movement is fine, but the moment I move my mouse away from the center, I get these issues. I suspect that it is because in these video games they "force" the mouse to always be in the center, and to perform movement, calculate the distance from the center, and then re-center the mouse. The problem might be that the mouse never re-centers.
Have you tried changing the mouse setting to "Optimize for games"? https://download.parallels.com/desktop/v19/docs/en_US/Parallels%20Desktop%20User's%20Guide/43133.htm
