I used yesterday PS and evrything was ok, while today the sofware doesn't recognize my AMD schede. Unfortunally the video schede is 4 years old and it's not possibile now to upload. Is there anyone who can help me? Sometime I solved the same problem uploading the old version of photoshop but I just checked and I'm using the newest possibile, so I don't think it's a question of PS's driver.
The driver isn't part of Photosho. What exact version of Photoshop do you have, please check.
The problem seems to be solved just closing and reopening the program.
Anyway my actual version is : (I'm drawing and pasting from photoshop)
"Adobe Photoshop versione: 2017.1.1 20170425.r.252 2017/04/25:23:00:00 CL 1113967 x64
Numero di avvii: 173
Versione: 10 o versione successiva"
