Hi I had the game in Beta version and it worked fine up, until the update for the warriors hero came in. After that point the mouse moves in a jerky fashion which makes the game annoying to play.

I've turned off every function that might improve performance and all my drivers etc are up to date.

Its the Steam version and the game is up to date, I've tried running the old Fallen enchantress and that's okay.

I've also tried uninstalling/reinstall a few times.

Can anyone help?
