A 2684 can take between 35 and 50 minutes per frame depending on your hardware.
and have folded at least 10 succesful regular (-advmethod) WU's before you can get the bonus for bigadv WU's
6061 is a regular A3 advmethods WU so thats perfect. It won't start to calculate the PPD until its done a few frames
Just wait till you've done 10 of them then you can switch the -advmethods flag off and the -bigadv one on.
What hardware are you running? Is it this?
There is a couple of tweaks that reduce cpu usage of the GPU client that Biffa should be able to point you to though.
100x better looking at that and i dunno what half of it even meansall i know i like big green numbers.
When i get the nvidia back will both run better then?
See here for member builds that run folding@home and seti
