I'm another 260 user who is having the issues, the new patch i tried today though not only broke the "mouse acceleration trick" to turn that crap off (no longer WORKS WTF?!) but also the .dll fix is now not helping at all and im still getting the same studdering as before but now its worse without the .dll working.. How do I revert back to an old version of the game? and can anyone get the mouse acceleration turned off? adding
fForegroundMouseAccelBase=0
fForegroundMouseAccelTop=0
fForegroundMouseBase=0
fForegroundMouseMult=0

and making it read only is no longer working for me. SO ANNOYING!!!!!!!

and yes i've updated drivers, yes clean installs, nothing wrong with my hardware ..i can play sc2 on ultra and other new games on ultra.. its obviously the game, not my computer..
