When I enter text in Photoshop CC for some reason it's jagged. I have gone to save default fonts, I've added fonts to creative cloud. I'm guessing I have to download the latest stand alone PS and use it rather than the PS CC. I had to do that with Dreamweaver to get all the features.
I suspect you have Anti aliasing turned off. Double click the Type layer, and look in the Options bar to the right of the aa icon. If set to None, use the drop down and select any of the other options. Perhaps Smooth would be good for you, but the differences are subtle.
