I run also POEM and SETI for GPU. So to download the WU's for Primegrid I have to stop them.
Normally I get a load of 25 WU's and I never have to stop the work for Primegrid, because the other two are quicker to load.
Yes, I have read that the work could be less because of the challenge, so I accorded GPU work for the challenge aswell. But from 25 to one WU a day is a big difference and probably not caused by the challenge.
Yes I have had a update of NVidia and I'm running the Boinc version from the World Community Grid. But I don't have any problems with it with the other two GPU WU's.
Only Primegrid gave no more work to crunch.
Firstly I will look if the World Community Grid has a newer version, because I don't want to have the newest BOINC version.
If that doesn't work I will look at Nvidia to get the right driver for crunching this stuff.
