I see multiple problems:
1) The screen capture does not match your stated ETH-only (single mining) configuration file. The miner is dual mining in the screen capture.
2) The miner is attempting to mine Decred (DCR) on a Pascal (PASC) pool in the screen capture.
3) Claymore v9.3 will no longer be able to mine DCR on any pool due to a change in stratum protocol. Claymore v9.4 or higher is now required.
4) The environment variables are not required for nVidia cards.
Try mining with an example launch file from the opening page of Claymore's thread. Please use Claymore v9.7. --scryptr
