Some are suffering more than others, I think the teams that based on CPU folders are fine, not much credit variance, but the teams that are designed around GPU folders seem to be tanking HARD!
Yup, mostly. Reason: CPU still include the BA-style of WU which were not that much impacted. Main issue was that for GPU based system the assignment server handed out lots "old" core 15 (nV) and core 16 (AMD) instead of the desired core 17 and 18. People don't like those because no quick return bonus and less PPD.
Plus the modern cards/driver seems to have trouble with the older cores. As a rough summary.
Patience ... And as soon we fold away all old cores they will not come back.
