this could be a general Adobe CC Question, but it's most prevalent in PS and extremely frustrating to work with:
I have a multi GPU System (4x GTX 1080) and a dual monitor setup (connected to card 1+2), Windows 10.
Photoshop keeps disabling GPU accelerated features like the drag zooming and panning, the color and brush size selection etc.
I tried a few solutions like app-specific nvidia system settings: Setting Photoshop to use only one card for CUDA rendering and using multi-GPU compability mode etc.
It works sometimes and then just disables the features mid-work. I allready read that there is some kind of disabling automatism going on with mutli-monitors multi-gpu combinations. How do I fix this? It's quite dissappointing to see CC struggle with setups that aren't that exotic...
Hope someone can help
Adobe specifically warns against multiple GPUs:
"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.
If you have to use more than one graphics card, make sure that they are the same make and model. Otherwise, crashes and other problems can occur in Photoshop"
Yes, that's true, but I do have multiple GPUs and I still want to use their products. I'm interested in workarounds/solutions.
Since all my cards are the same model I will try plugging both monitors into the same card as suggested in their statement.
I think we can agree that this isn't really an acceptable state of this software to just flat out drop features with better pc specs...
If in my case i have a laptop, that options works too?
Most likely yes... Obviously some what dependent on your specific setup:-)
I have been having problems with this bug through the last 3 PS updates, as well as scrubby zoom and Rubylith not working after the update(s) even though I had prev. set my ASUS laptop (dual card) to use the more advanced NVIDIA card & settings. The key, for me at least, seems to have been adding PSsniffer.exe to the list. After adding that all three of the problems have disappeared. Fingers crossed that they stay away:-)
This on a NVIDIA GeForce 940MX and cashe levels set to 6.
