I'm an rx 480 crossfire user.
I expected the 16.12.2 version of the Crimson driver that was released, but from the release notes, the chill feature is still not enabled.
I installed the driver myself, but there is still no chill function.
When can I use chill in crossfire?
When AMD gets it working. As it stands now Chill only works in select games, so there's plenty of refinement to keep the driver team busy for a while to come.
