Can't enable GPU options in v22 - NVIDIA Quadro P1000

Question

Have a user with a HP ZBook Studio G5. It has an onboard Intel 630 and an onboard NVIDIA Quadro P1000.

No issues in v21 but as soon as they've upgarded to v22 they've lost the option to select use graphics processor.

Drivers are all up to date. The NVIDA has an option, Manage 3D settings, where you can assign which card you want to use for individual programs. PS and sniffer are both set to the NVIDA.

If I disable the Intel card completely the option to select graphics processor returns and everything in PS is fine however they user reports that causes display issues elsewhere.

Roll back to v21 and it all works but the user wants to use v22. Is there anything I can do or is it just hoping for an updated driver?

This has been a problem ever since the first dual-GPU laptops came on the market several years ago.

I'm sure you know this, but many others reading this probably don't: The basic problem is that Photoshop uses the GPU for actual data processing, and the result returned to Photoshop. It's not a one-way flow like it used to be. So Photoshop needs to know which GPU to talk to. The question is whether the laptop manufacturers know this...

You'd think it would be a simple matter to "lock" Photoshop to one GPU and tell it to ignore the other. Since this hasn't happened after all these years - and Adobe cannot possibly be unaware of this - it's apparently not so simple. Maybe the necessary APIs simply don't exist.

New versions tend to introduce new error-checking code, as new GPU-resident functions are added and specifications change in the new version.
