Why does FAH throw out work with a new graphics driver?

[CaptainHalon]

I've noticed this a couple times. Maybe I'll be 50% through a work unit, I'll shut down FAH, update the Nvidia drivers, and restart FAH...then it starts over from 0%. Why?

[JimboPalmer]

Hmmm
I pause the Work Unit I am working on, then go back to folding after the driver is updated. I lose up to 5%, just like anytime I pause a WU.

[CaptainHalon]

Ah, not mine. It goes back to 0%.

[Neil-B]

A reboot after installing the nVidia drivers will ensure FaH picks up the new drivers ... It may be that both this and the other issue you post are linked to FaH trying to use old drivers after driver update?

[toTOW]

Which OS do you use ?

Do you use drivers downloaded from nVidia website (and not from Windows Updates) ?

When I update drivers (which doesn't occur very often since FAH doesn't need all the game ready updates), I do the following :
- download drivers from nVidia website
- exit FAHClient
- update drivers
- reboot
- restart FAHClient

[Joe_H]

Examination of the F@h client log files from before and after the driver update may give a clue to what problem is being seen with the WUs causing them to be restarted from the beginning. Otherwise everyone is just guessing. In general updating the drivers should not cause this to happen.

[CaptainHalon]

Yeah, I use latest drivers from Nvidia's site. I'll check the log next time I see it happen and see if there are any clues.

[aetch]

Depending on which OS your running your working folders could in one of three locations:-
Windows up to FAH Client 7.6.13 - C:\Users\<username>\AppData\FAHClient\
Windows FAH Client 7.6.21 - C:\ProgramData\FAHClient\
Linux - /var/lib/FAHClient/
By default your current log.txt file is stored in the parent directory and your previous 16 logs are stored in a subfolder called logs.
