P: Zoom and Pan performance is poor since a couple years.
I've been dealing with this problem, I think for years before I'm finally mentioning it. Basically, a couple years ago, Photoshop developed a slight delay when I begin to zoom, or pan. It's very slight. Maybe most people wouldn't worry about it but here is the problem that it causes. When doing things like digital painting, I'm working very quickly. I pan, paint, zoom, paint, rotate screen, paint, pan, erase, etc. All of this with a great fluidity, as long as the system is keeping up. In Photoshop, I paint, pan....it didn't actually pan but I went ahead and painted a stroke. There's a pause as Photoshop thinks, or tries to catch up then suddenly it makes a paint stroke, but it missed the pan movement. I zoom then paint but it skipped the zoom and makes a paint stroke in the wrong place. It missed the rotate and caught up with the erase so it erased in the wrong place. The cure for all of this for me has been to actually work more slowly in Photoshop to allow it to keep up! The other thing I began to do was to not use Photoshop for this work. I instead began to use Clip Studio Paint which is just wonderfully responsive. There's none of this kind of trouble in Clip Studio Paint or other software for that matter. Also, Illustrator's zoom and pan are much more responsive. Photoshop has a problem and I wonder if Adobe understands that it's a big enough problem to actually resolve it.
