Just bought The Missing Link DLC only to find that it has some sort of Mouse Acceleration/Smoothing.

I was able to edit values in the reg files for Deus Ex:HR to get rid of it there but I can't find anything in Regedit for The Missing Link.

Turning off V-sync and every thing else doesn't work, I'm sure this is built-in acceleration and not input lag.

Anyone know of a proper fix, something that straight up turns it off? Anything else is useless. At this point i'm pretty pee'd off as I already spent £8.99 on DLC I knew only lasted a few hours and was reluctant to buy but now finding out it's unplayable (For me anyway, acceleration/smoothing ruins games for me, others don't mind it but I just find myself gritting my teeth whenever I try to play a game with said options).

I hope I can get this resolved, both because the DLC looks fun and I don't want £9 to go to waste, especially since I'm not exactly loaded.

Thanks
