It seems we have a true slugfest between AMD and Nvidia, and instead of it being video cards this time its with drivers. AMD has released a small preview of drivers they seem to be working on for the BattleField 3 beta going on now, which answers my earlier question.
- Improves performance in Battlefield 3 Open Beta release for both non-Anti-Aliasing, and application enabled Anti-Aliasing cases on the AMD Radeon HD 6000 and AMD Radeon HD 5000 Series for single GPU configurations
- Enables support for Eyefinity 5×1 display (portrait and landscape) configurations using the AMD Radeon HD 6000 and AMD Radeon HD 5000 Series
- Vision Engine Control Center: User Interface enhancements have been implemented for the CrossfireX, GPU Overdrive, and Information Center pages.
