I have a strange issue with 8 GPUs on Windows 10 (1709, x64). Using 8x 1070Ti when starting up ccminer it only hashes on 1-3 GPUs. It then takes several minutes until all GPUs start working.. sometimes an additional one starts every minute, sometimes suddenly after 5 minutes all of the rest start hashing. First noticed it on mining PHI, but the same behavior also occurs with other algorithms.

something I noticed is that it sometimes prints one last "Intensity set to ...." message before all GPUs start mining, but not always. maybe that is related to the delay?

is there something that can be tweaked or done to make all GPUs start up quicker?

happy new year!
