Running one GPU for gaming and one GPU for mining simultaneously? in Graphics Cards Posted March 3 Just now, Purgent said: This is not correct. A dongle is not needed. You can point the mining software to any installed card. I said *may be needed* as I have had issues with it in the past and have found other examples of the same issue. Not specifically with mining, mind you (with other GPU compute workloads), but nowhere did I affirm OP *will* need a dongle.
