The first update arrived in February this year and while there were multiple Radeon Software Adrenalin driver releases for users of discrete AMD GPUs, but the APUs had received none.

It had been believed that AMD was going to integrate the Raven Ridge updates into the main discrete driver branch.  However, over the weekend, an AMD employee AMDMatt, chatting on the Overclockers UK forums said that AMD Raven Ridge GPU driver updates will come at quarterly intervals.

In answer to another forum user's question  "How come there is no raven ridge support with the last two drivers? I thought they were now unified release?" AMDMatt replied: "APU drivers are updated every three months as WHQL releases only." Several forum users expressed their disappointment in the scheduling but there was no further comment from the AMD employee on the matter.

One user pointed out that there was no point having an APU if its possible that a game could perform much worse than it's meant to as you've got to wait three months for drivers.
