Fill and sign performance issue I do software testing for our enterprise environment before we deploy to our users. Fill and Sign is a feature that was long overdue and it's finally here. While I am happy at the performance of the new Reader DC reader and Acrobat DC opening and loading documents is much improved, but there is one area where I don't understand why there's a marked difference between Acrobat DC and Reader DC. I am testing using a Surface Pro tablet with Windows 8.1 and it's included stylus. When you use the Fill and Sign tool, drawing a signature in Acrobat DC works beautiful. The signature drawing comes out great and it feels very natural to draw, sign, and use handwriting. However, in Reader DC, using the same exact document, drawing the signature has a terrible lag, and it misses strokes, as a result the signature has barely any resemblance to what it is supposed to look like. That is unless you draw the signature really really slow to give time to the software to catch up to the curves as you draw
