We just added RavenCoin (RVN) mining for AMD / Radeon GPUs!
In order to enable it please download the latest version of BetterHash from our website, then make sure you re-download all miners because there's a mining executable update as well.

P.S. In order for profit switching to take into account the newly added RVN for AMD / Radeon GPU you will have to run a benchmark.
Enjoy!
