AMDs RX 580 not supported o well. I'm seeing some improvement with the CPU render time it is a little wanky crashed once, hair really bogs it to a crawl with lefem hair in a scene 8 m deleted the hair only took under a minute, Progressive Refinement does not display right as it renders squares and the top shows up at the bottom half of the render, it finishes fine when completed. I'm liking the snappyness of the program, before it was boggy when moving something in a scene. ok I'm tired ill mess with it tomorrow after I vote.
