I can't use zoom function with Mouse Scroll Wheel button. (checked Photoshop > Edit > Preferences > General) With previous version, I use 'Alt + Scroll Wheel button' for fast zoom. Do you have same problem ? My system: Windows 10 x64, Photoshop CC 2014 version 20140926.r.236 x64, Intel HD Graphic 4600 Sorry for my bad English. I'm not native English speaking.
