Well, according to Photoshop graphics processor (GPU) card FAQ , you're well within specs for Photoshop, so perhaps there's an issue with the driver? May I assume you've updated to the most recent for your system? One more thing to consider - 2gb vram is great for most 3d applications, but if you're opening a document with a LOT of math, perhaps that file needs more?
If those issues are all in order, I'd request some help from Adobe themselves, as they may be able to troubleshoot your specific issue - or make a ticket, in case there're more people experiencing this problem with the more recent upgrade...
Rich has two graphics cards, the high performance AMD and the Power saving Intel 530. Usually the default is "automatic" switching between the two which sometimes doesn't work.
This section shows how to solve that problem by choosing the AMD Card as the preferred card.
This is correct. The computer is also a desktop, which means that the automatic switching function that is referenced in the troubleshooting is not a feature, as it is only available for laptops as part of the power options. That leave the option of disabled the integrated graphics which is and unacceptable solution, as i need it to support my workstation's screen. I have also verified that windows, Photoshop and the relevant drives are up to date with the manufactures.
This issue lies in the underlying application, and the sniffer.exe (or another component) crashing during execution. I was hoping someone from Adobe might want logs or crash dump files of some sort that might help them diagnose the issue.
I too have a desktop computer, running the latest Windows 10 (creator) and Photoshop CC 2017.1.1. After the recommended AMD graphics card (R7 200 Series) did not work with PS, I installed their Crimson 17.7.1 which worked fine with LR but again, PS crashed and then booted up but had disabled the graphics card because it could not detect any card. Needless to say, it took some time to try to figure out what was wrong. To cut a long story short, when I looked at the Radeon settings, I noticed that my TV which is connected to the computer was listed as primary monitor while the computer monitor was considered secondary. My guess is that PS only looked at the primary monitor, the TV and could not find a card. When I set my computer monitor as primary and the now turned on TV as number 2 (which it should have been to begin with), PS detected the graphics card and all is well, for now.
I don't know whether my experience is helpful to anyone with more than one monitor or with a connected TV but perhaps it is worth a try for those who have not found other working solutions.
