I recently purchased a MS Surface Pro 3. For some reason the user interface is smaller in Photoshop than any other Adobe program. The experimental 200% UI preference makes Photoshop FAR to large. I don't know what Adobe is thinking.
All of the other Adobe app interfaces are a nice usable size. Is there any way to get the Photoshop interface to be the same size as other Adobe apps?
We're still working on the HiDPI implementation. At this point the experimental preference is either on or off.
Hang in there, we'll provide an update when ready.
