I've noticed now several times that my mouse speed will change while playing some times. I like it faster and suddenly while fighting some times, it will slow down. I then will change the setting on my PC overall to make it faster. It will stay that way for a while and then suddenly later while playing, the game will make my mouse speed way too fast.

This continues to happen. The only change I've noticed that I make sometimes is the key bindings. Otherwise, I'm not doing anything other than playing.
