Wait, hold on. Isn't mouse lag on win8 is a known issue? There was even a patch from MS that fixed few games but I hear the problem still exist.
Anyway, is that 64b version?
Never had a problem with the mouse until this game. And, yeah, 64b version.
As an addendum I would like to add that as soon as I lowered quality to Medium from Ultra the problems occurred significantly less. They still happened but it was not nearly as often and allowed me to get quite a bit further in the game last session.
Graphic quality is not an issue for me and so I'm quite content with leaving it there but felt I should point that out.
@Raze: Okay. Will look into that support tool and get right on that. Thanks and sorry. Admittedly I just jumped into the Alpha and had not really combed the forums at all.
