According to a report from IGN, EA and AMD have entered an agreement which sees the latter benefiting from exclusive rights to optimization for games based on EA's Frostbite 3 engine. Titles like Battlefield 4, Need for Speed Rivals and Mirror's Edge 2 are subject to this rumored accord between AMD and EA, but also many other current and future EA titles. Of course, this will not completely remove NVIDIA from the Frostbite 3 table, they will simply be absent from it until the actual launch takes place, meaning that pre-launch testing and driver optimization can only be done by AMD, leaving NVIDIA at a clear disadvantage.

While sill an unconfirmed rumor, AMD refused to deny it in a reply to Ryan Shrout's query regarding the story. AMD's reply below.
"It makes sense that game developers would focus on AMD hardware with AMD hardware being the backbone of the next console generation. At this time, though, our relationship with EA is exclusively focused on Battlefield 4 and its hardware optimizations for AMD CPUs, GPUs and APUs."
