So, I had a PC with a GTX1080, used for folding. I have just added a GTX 1660 Ti in the secondary slot, which I intended to use for folding as well. But all the signs are that only the GTX 1660 Ti is folding, and the 1080 is not. I have updated nVidia drivers and the latest Folding software to v7.5.1 with no change. Do I need to change something to get both cards to fold? Pre v.7 there was a strange 'feature' so that if two cards of different generations were used then both cards would fold, but at a slower than normal rate. Does v.7 automatically avoid this by only using one card?
