Hard to say, as the version we all got yesterday through Windows Update from MS is a different version than the latest release or this beta on the Intel site.So to confirm, other than support for Titanfall and Thief, this Intel graphics driver beta version x.3464 is no different than the version x.3431 included in the SP2 March firmware update released yesterday?
I'd stick with the MS driver at the moment unless you want to play Titanfall, in which case you must install the Beta or else the rendering glitches make the game unplayable.
