Weird Sensitivity Issue

so I play on a logitech g pro gaming mouse at 800 dpi and 4 sensitivity and this has been perfect for me.

Last week I noticed that randomly in game my sensitivity felt way too jerky and fast for seemingly no reason, so I lowered it to 3.75 and everything was fine.

now 3.75 is randomly way too slow like playing through molasses, and my mouse feels weirdly floaty and unresponsive. Everything feels fine in the menus but in the practice range and in games I can definitely feel the difference.

I pulled up ctrl + shift + n and didn’t notice any issues with my latency or my fps dropping (although I did have some issues when the summer games patch dropped for a couple days).

I’m just wondering what I can do to troubleshoot the issue or if anyone else is having this problem.

thanks!
