I hope you are doing well. I have to say thank you for creating the mouse fix mods for Metro and Mass Effect. They really improve the gameplay experience. I was trying to use your MWR Fov fix to replay some modern warfare and it turns out the fix doesn't work. I don't know if you have checked the comments on your webpage but recently someone left a video showing what the problem with the FOV tool might be. I hope you are able to fix it!
Have a good one,
