Hello! check this out:
https://mega.nz/#F!uhQR0IRa!jZ_tdULPoUf3ib4O6-1BoQ this is a special version, basically the same v0.3, but with a modified device launch system. Please note that if you do not have a problem with starting up devices, do not use this version!
@EWBF_ hmm after i take this new test version miner it start running what it make me think in other version when it use --cuda_devices 0 & there are 2,3 gpu in reality miner it was not deselect other one coz check this:
--cuda_devices 1 (2 GPU) - v0.3 normal version
