Photoshop CC 2015.1 is laggy when rulers/guides are on.

Someone suggested turning guides off as a way to improve performance and surely enough scrolling, panning and zooming is considerably faster without rulers and guides.

Would you please fix this? Guides are kind of important.

Please install the latest Photoshop updates.

And what OS version are you using?

What kind of system are you using (because this might be GPU specific)?

I have a fully upgraded 5k iMac with an AMD R9 M295X - 4GB.
Scrolling around in PS however has been slow with every computer/PS version I had and for longer than I can remember.

There are others suggesting this also, but I see you are already aware of that topic: http://feedback.photoshop.com/photosh...

Does it work well on any of the systems you are developing on?

Photoshop is not normally that slow.
But we have seen video driver bugs, occasional OS bugs, some third party bugs (plugins and other apps), and a few times an actual Photoshop bug (which we fixed quickly) cause slowdowns with rulers.

Your iMac is an odd case, because the built-in GPU really can't keep up with that screen space, and so small problems are magnified by the larger screen drawing area.

Yes, it is working well on the thousands of systems we develop and test on. But we'll double check your machine and OS configuration and see what we can find out.

The GPU can keep up with immensely complex PSD files but not with Guides? Scrolling around with guides on was laggy on my old computer too, which had a Radeon 6670 and no retina display.

What about all the people who confirmed this in the other thread?

That GPU is pretty slow for such a large display, and yes, it is slow even showing images. But the fact that it is slow amplifies any slowdowns due to drawing items on screen (because it has more pixels to render). The GPU doesn't do anything with the complexity of your documents -- it just displays the composited result.
