mfaktc throttling / deprioritizing

[TheMawn]

Hi, folks

I use my PC for a lot more than just helping out with GIMPS. I have my whole i5-3570k helping the cause, as well as all the capabilities of my GTX 670, which is actually a bit unfortunate because a lot of what I do demands a trivial amount of GPU capacity, but mfaktc is very reluctant to give any up, which means choppy videos on Youtube or Twitch.

Prime95 barely affects anything at all because it runs with super low priority. Is there a way to tell mfaktc to allow other things to get dibs on my GPU and have it pick everything that's left over?

The key thing is to reduce the GPUSieveSize. You can do it manually, with a batch file, or with Mini-Geek's application.

in the mfaktc.slow.ini the value is GPUSieveSize=4

in the mfaktc.med.ini the value is GPUSieveSize=16

in the mfaktc.med.ini the value is GPUSieveSize=128

You can use whatever value(s) you want. The key is having the three ini files in place.
