FPS Drops on mouse input in some games with EAC

[Nikitron31]

Game: Fall Guys
Problem:

1. FPS drops on mouse input (just WASD or afk = 144 Hz const)
2. After exiting the game, the anti-cheat says that rbtray dll is untrusted

Fun fact
If you connect a second mouse together with the first or just change the mouse (in my case I took a very old and very simple mouse), then there will probably be no more FPS drops

I have this same issue, but in Dead By Daylight. FPS goes to 0 when moving mouse and the game only unfreezes after stopping mouse movement. Same EAC error but it usually doesn't show when I exit, only shutting off the pc while the game was running got it to pop up and led me here. Never would have guessed that it was RBtray causing it otherwise.

Plugging in a second (very basic one here too) mouse did nothing for me though.
