+ As some have issues with miner 'just waiting some time' on startup, i added more logging option so we can catch where it hangs, and i can possibly fix that

ok, now i know its not the new devfee method that is problematic.
But i would suggest to try now a previous version that you know was working good.
Nothing was changed in the new version in the GPU's initialisation process (this is where it hangs), so my guess is something at your side is causing this.
