Photoshop cc 2018 completely unworkable so far

[jjaylad]

Installed latest version last night. Tried a simple select and mask process tonight after seeing so many people praising its improvements.

Complete disaster. Worst selection ever, Worse than 5 or 6 years ago. Half the 'views' wouldn't work, quick select tool properly sized was picking up stuff 2 feet away from person's head despite good contrast between subject and background. Refine edge tool only makes it worse ..removing almost everything it touches. I've used selections for years and have never seen anything this bad. I tried disabling the graphics processor and that slowed it down even more.

With only one image open, with only two layers my PC nearly stalled. I closed LR and had only PS open with the one image, and went from 30% of my 12 gigs of ram used to over 80% with just a few brush strokes and within a minute I literally couldn't do anything.

Not a chance this is going to work. Good thing I hadn't just shot an important job with a deadline. I am in shock. How do I get my old Photoshop back to use until the new version has the bugs out of it? I'm just kicking myself for installing so soon after it was available. The many positive videos etc. brainwashed me into believing this upgrade would work.

Is there a simple way to revert to the last Photoshop CC version?

I should have titeled it 2017 not 2018.

Further to this Photoshop isn't recognizing my graphics card. It is only recognizing the base Intel graphics card in my laptop.

According to the support documents for Photoshop 2017 it should recognize nVidia GeForce: 400, 500, 600, 700 series.

Mine is the 740M but it doesn't even come up as one to select in the Preferences/Performance where only the base Intel card is listed.

Hi

It looks like you are having some issues. The select and Mask issues are probably releated to the GPU issue you mentioned in the second post. Photoshop has always had issues where multiple GPUs are installed. See section 7 in the attached link which may help you to ensure Photoshop uses your NVidia card

Troubleshoot Photoshop graphics processor (GPU) and graphics driver issues

In addition, if you still get problems with S&M try unchecking Use Open CL in Preferences >Performance > Graphics Processor settings > Advanced.  In theory this should only affect speed , but I saw an issue yesterday where it had a large impact on the quality of the selection.

In addition to my last post , you asked how to get CC2017 back.

If you open the desktop app and choose the down arrow next to the Open button for Photoshop you can choose "Previous Versions". You don't have to uninstall CC2018. You can have several versions installed on the same PC.

Thanks for the replies. I did speed up somewhat after 4 or 5 rounds of use. Almost like it has to rebuild an index or something.

Still disappointingly slow and I honestly don't find the selection tools any better than earlier versions and using them really bogs my system down and really absorb available ram to the point of forcing the closure of lightroom and anything else open.
