Do the 4.2 tasks need/make use of as much of a CPU as the 3.1 tasks? I've been watching a 4.2 task run on my GTX 570 and noticed that the CPU utilization by the core I've set aside for GPU tasks is much lower than before... Still looking for feedback on this. :-) |

As you observed, the new app appears to use less CPU. Remember that different tasks use different amounts of the CPU, so things could change as and when new task come and go. FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help |

Yes, if you have plenty of cores/threads (4/8 for example), and for stability reasons as well as performance. FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help |

I am still receiving an occasional 3.1 long run task on my main PC, have selected only to receive long runs. I did the workaround but somehow it reverted to the original 3.1 executable. |
