I have a WIN10 machine (2700x CPU) with a Nvidia 1060/6GB as well as AMD RX580 video card installed. I have been testing my new copy of PL4 and DeepPrime exports.
With the preferences set to using the Nvidia card I can export single photos as well as multiple photos in batch.
However, if I select the AMD RX580 card in the preferences I can only export single photos at a time. If I batch select multiple photos I get one successful export and for the rest I get the error message:
Save has Failed Internal Error (Correction failed on the execute stage)
I have WIN10 v 2004 and the latest drivers for NVIDIA and AMD installed. My monitor is connect to the NVIDIA card. The AMD card is installed but does not have a monitor attached.
