It turns out that my computer got into that state somehow and was recoverable by rebooting the computer.
I'll post back if there is anything forge related that gets it into that state but at this point I think it was just too much back and forth between my mod development and testing for release.
I have only Forge 11.14.3.1519 loaded (no mods) and in the game you can barely control POV. Just up and down. Its like the mouse sensitivity is set to max. When lowering the mouse sensitivity it doesn't help.
I tried loading vanilla and it doesn't have this issue.
Will start backtracking with earlier Forge versions to see when this started. Unless someone knows why this is happening.
