Thunder - thanks for solving this for us
We`ll include this in the knowledge base!
About in-game resolution, DoF right now supports 1920 x1080 at most, any resolution above that will create problems.
@ Zanderscotx - can you confirm if Thunder`s solution works for you? Simply adjust Windows Font size settings in the Control Panel and sounds like it should fix the mouse issue.
And sorry for the inconvenience guys - I know it sucks to change win settings just to play a game, we`ll aim to have a permanent solution with-in two weeks.
