Good evening.

I've not even had chance to play this yet, as both times I've launched it, after a few minutes every control seems to fire off at once.

First happened following a benchmark, once I exited the results page, it was constantly cycling through the menus wherever the mouse cursor was.
The second time happened during character creation. Same thing.

I am running the game on the following:

Intel i7 7700k
Asus ROG Maximus IX Formula
Asus ROG Strix GTX1080
Corsair Vengeance 32GB DDR4 @3GHz
Asus Claymore (full) keyboard
Asus Spatha Mouse
