I tought it would work now after OR update. Not going to throw it anytime soon as i just bought it few weeks ago :) Anyhow, i just loaded newest amd drivers and it seems to be bit smoother now, most of the time 45fps. I still have some options to lower from graphics if i feel the need to do so.
Also going to add some more memory and new cpu at some point, maybe it'll give some fps more...
