Windows 11 Preview Build Mouse FPS Drops

Hi, I'm on Windows 11 preview builds and am having a performance anomaly. With a series x controller connected, I can run the game at what I was previously getting on Windows 10, which is around 70-90 FPS in most areas. However, on Windows 11, using the mouse at all in game now seemingly drops the framerate tremendously. When I initially starting having this problem yesterday, I had assumed that the problem was my CPU, because I had made the connection that moving the camera is what drops the FPS, which is an issue I've had in particularly CPU bound games before on older laptops and such (the old days of Minecraft optimization on underpowered laptops, moving the camera around drops frames). But I decided to test it with controller and no, sure enough, playing with a controller causes the game to stay firmly in a 70-90 FPS range in most areas. Taking my right hand off the controller and using the mouse to move the camera around then instantly drops the FPS to around 45.
