Einstein GPU - drop in PPD

[MGP]

Over the last couple of weeks I've seen my output drop quite a bit. Don't think I've made that much of a change to my systems in terms of time they can be crunching or what other projects. But the PPD is down by some 50%.

I mainly run Einstein's GPU stuff, on Nvidia cards. What I have noted is the Parkes WUs seem to now take many many more hours to complete.

I'm trying to vary the number of WUs in progress at once using the Einstein settings, but I'm not seeing much benefit if I reduce or increase 1 / 2 / 4/ even 8 (doesn't really like the latter).

Anyone got any thoughts or do I have to live with poorer PPD?

Either they have changed the wu so they take longer with no increase of points or maybe you have updated the drivers?

I think the problem is the virtual Boinc thingy. Having stopped that the PC as a whole is performing better, and predicted times for the GPU stuff are tumbling.
