I have the problem, that my AMD R9 390 Nitro (sapphire) is not recogniced by my Photoshop CS6 neither. Neither Photoshop CC nor Premiere Pro CC recognice my GPU.
I have no idea why it is not working. Lightroom CC on the other hand recognices my card.
More information on the picutres.
same here. I patched from 17.5.2 to 17.7.1 and now it can no longer see my vid card. Lightroom and all other adobe products working fine
