I want to report an issue that I have experienced since 2014 photoshop it first came out. namely, photoshop CC 2014 was very slow when I use it, in contrast to photoshop CC. I attach the following video that I made a few months ago: https://www.youtube.com/watch?v=Edd0bFVHln4
I have reported it on the forums, I think the latest update will fix this, I have to update to 2014 photoshop: 01/02/2014, it turns out this issue is encountered. currently I use a macbook pro late 2013 2.3 Quad core, 512 gb SSD, 16 GB Ram.
