Question

Photoshop performs slow, Graphics card confusion

  • July 21, 2018

Hello.

I'm operating Photoshop CC on a Samsung Notebook 9 Pro Touchscreen laptop.
It has Intel Core i7 16GB of Memory; 256 GB Solid State Drive
It has 2 graphics cards, AMD Radeon 540 and Intel UHD 620.

My problem is that Photoshop has severe brush lag when I have 'Use Graphics Processor' checked in the Performances menu.  When I uncheck it, the lag goes away, but other problems happen where sometimes the screen will have an artifact visible until I minimize and then maximize the screen.

I'm truly baffled and at the end of my rope with this problem, as I am a product designer, I rely on Photoshop for my work.
I'm also having a problem with Illustrator CC, where the program is slow (I've used it since 2008 and it's never been slow).

I don't know if my computer having 2 graphics cards is confusing the Adobe programs, but I am at my wit's end and any help would be appreciated.

Okay, so I checked that out.
Apparently my AMD card is the more powerful of the two that I have.

I have the AMD card set to be used in Photoshop at High Performance.  However when I check out the System Info section on Photoshop, it states that the card used is the Intel UHD 620 (which is the other card).  When I open the Intel card Settings, there are no programs assigned to it.

I think that somehow, Photoshop wrongly thinks that it has to use the Intel card, even though I assigned the AMD card.
I'm not sure if there's a way to fix that, or if the only way is to disable the Intel card.

I'm nervous that disabling the Intel card will give me a blank screen.

Photoshop graphics processor (GPU) card FAQ

Photoshop currently doesn't take advantage of more than one graphics processor. Using two graphics cards does not enhance Photoshop's performance.

Multiple graphics cards with conflicting drivers can cause problems with graphics processor accelerated features in Photoshop.

For best results, connect two (or more) monitors into one graphics card.

As for general Performance related advice:

Thank you for the response.  I am not the most tech savvy person, so I'm not sure how that helps.  I don't have an extra monitor to hook up the other card to.

Are you saying you are using 2 GPUs for one monitor?

Because the Photoshop related advice would be to only use one GPU total.
