Dear community,
I have run into this problem a while now, for past Photoshop versions as well as the newest. Only recently I found out why. The mistake is exactly replicable, I've done it multiple times and everytime it repeated. I did the following:
1. Open LR
2. Open PS and check whether a GPU is detected -> no
3. Close PS and try again
4. Close LR and try again -> GPU detected
I have done everything that I have seen posted on the community about GPU issues (update driver, set preference to GPU, etc.) but nothing worked.
The GPU is a Quadro P1000.
Thank you for reading this.
