Photoshop 25.1 (and Beta 25.2) not supporting multiple GPU

Ps latest version (25.1) doesn't detect my GPU.

Upon starting the application I get this warning:

And when going to Preferences > performance, there is no GPU detected at all:

 

My Nvidia drivers are up to date (Studio driver 537.58), and I performed a clean install to make sure it was not driver related. I also did a complete cleanup of all Adobe apps, using the Adobe cleaner tool, and only reinstalled the creative cloud app and Photohsop to isolate the issue.

If I disable one of my GPUs in the device manager, then Photoshop runs fine and detects my GPU. If I rollback to the previous version (25.0), Photoshop runs fine with both GPUs enabled, no issues. All other apps run perfectly fine with both GPUs enabled as well.

 

That seems to indicate Photoshop 25.1 (same behavior in Beta 25.2) does not detect a GPU when there are multiple GPUs installed, or at least it doesn't support my specific configuration:

 

Windows 10 PC

Core i9-10900K

64GB ram

RTX 3090 (Main)

RTX 3080

 

I've spoken to several adobe agents, over 3 remote support sessions and nothing was resolved.

    In case that's any help - the latest update (25.5) has resolved the issue!

    Bumping this thread up, as the issue is still unresolved after 4 updates...

     

    The way PS detect/access the GPU(s) was broken in version 25.1, and remained so in every updates up to the latest (25.4). It appears multi-GPU support was dropped or at least it broke on my multi-GPU configuration, which is nothing too exotic: RTX3080 + RTX3090 running the latest Nvidia Studio drivers.

     

    I tried every updates and ran into the same 'No GPU detected' issue, and so I keep rolling back to version 25.0 which runs fine on my system.

     

    Anyone else having this issue? Or anyone running a multi-GPU config without issue? Last I raised a ticket with support I was told to wait for the next update... There's been a few since then, and the problem hasn't been addressed.
