Has anyone tried leaving this setting "Enabled" for a few days to see if it will run the tasks twice as fast? | |

Been running mine today like that, and I think it's limited to 240 of 480 cores while on. The one task I'm running right now is 25% done after 2 hours wall clock time. Kinda sucks considering that every time I disable Multi GPU Mode, my machine freezes during reboot.. Guess I need to revert to 32bit XP where I last had Multi GPU off and problem free.. grr.. | |

It took two days until I noticed that I had to disable multi-GPU mode. :-| | |

Indeed, in multi-GPU mode it works only with 'half steam ahead'. Thanks Dieter, unfortunate - I'd love to just run one task at a time much more quickly. | |
