Radeon RX Vega primitive shaders will need API support
Some controversy has arisen today regarding the state of primitive-shader support on Radeon RX Vega graphics cards, stemming from a post on the 3DCenter forums.

Some have questioned the validity of this single source, so I wanted to back up this statement with my own breakout-session experience during the company's pre-CES tech day. At least in the session I was present for, AMD gave us a surprise update regarding the status of various Vega architectural features after I asked about the ongoing confusion regarding the status of primitive shader support in the latest Radeon drivers. The company may have offered that same briefing to other members of the press in other sessions, as well.
