Back again with this stuttering problem, i was running to these days the BC driver but tried to update to 19.4.3 and same stuttering again. None of the drivers work after 18.?.?
Rig works with 4 cards but after connecting fifth or sixth card, it starts to lag and cant run claymore and again BC driver works perfecly but can't use -strap option

Does anyone know fix for this?
Ok I will add blockchain driver support in upcoming version.
