Close Chrome. In windows explorer, navigate your way to your Chrome profile folder, named 'Default', then rename it. Something that makes it look out of place, like 'sausages', is good.
C:\Users\~your username~\AppData\Local\Google\Chrome\User Data\Default
Now open Chrome and it will create a new profile for you. If the game now runs okay, then something is screwed in your 'sausages' folder.
If the game is still messed up then you can delete the new default folder and rename the 'sausages' one back to 'Default'.
