I have been experiencing huge slowdowns in Illustrator, Photoshop and InDesign with my NVIDIA GTX 970 graphics card. It has been suggested, that AMD cards do not cause this problem, so I bought and mounted a AMD Radeon RX 460 on my system.
So now I have these two cards, both work, but what I want to use for Adobe Apps is the AMD. I know that Photoshop only receives a list of OpenGL-capable cards on the system and picks one - the first one, alphabetically - from that list. It does not do any actual chosing. That is what the BIOS / Drivers do.
My problem is, that the GeForce is always first in this list and I can never get the Radeon to be used, unless:
- I disable it in Device Manager
- Start Illustrator, Photoshop or what have you on the one remaining display
- Re-enable the GTX in Device Manager
- Never quit the program, unless I want to go through the rigmarole again.
My question is, can I get the GPU-Sniffer (that's what the thing is called) to detect my AMD card and then somehow disable it from re-detecting the other card?
