just updated from 16.3.2 to 16.7.3 on an a8-7560k with r7 250 in dual graphics. Prior to updating this it work flawlessly in dual graphic mode. Since update minecraft and starbound, both of which I think us java crash the display drivers when attempting to launch. have to change global settings to turn off crossfire to play these game on this machine. Does anyone know another workaround to keep dual graphics enabled? !
