I wonder if the F@H folks made some changes in what WUs are assigned to AMD GPUs. Over the last few days, I have started to see some nice WUs again on my Fury X. The last couple of months was a steady supply of 94xx and 9842 WUs, but now I am starting to see the big 11432 and 11713 WUs again.
An example of the huge difference in PPD of the small 94xx WUs, and the large 11432/11713 WUs, running on an AMD GPU:
p9415 - PPD range = 320-337k PPD
p11432 - PPD range...
